Abstract
The possibility of a shared development path, together with a common language and culture,
suggests that it is useful to examine the determinants of earnings in Taiwan and China. Using data
from the Chinese Household Income Project and official household income survey data of Taiwan we
estimate the distribution of earnings in Taiwan (1978–1995) and China (1988–1995). In spite of
differences in the trend in earnings inequality, we find converging levels and returns to education
between the two countries. In contrast, returns to experience appear not to be converging, most likely
due to China’s dramatic economic restructuring.

1. Introduction
Market-oriented economic reform, which began in 1978, has brought varied and
substantial changes to the Chinese economy. Among which, the change in the wage
system is the most noticeable and economic inequality has become an important concern.
Before the reform, China was a completely centrally planned economy in which the labor
was bureaucratically allocated and wages were administratively regulated. The egalitarian
wage system eliminated or minimized wage differences across regions, occupations and

genders. However, things changed dramatically since the recent market-oriented economic
reform and inequalities in the distribution of income in China began to appear. This is
partly due to the policy of ‘allowing some to get rich earlier’ on the premise that ‘advanced
and richer region could help less advanced and poorer region and both get rich together
later.’ It is generally recognized (cf. Nee, 1989) that as the economy transitions from a
redistributive economy to market economy, producers are paid more closely according to
their individual productivity. Thus, we anticipate more income disparity under the more
flexible wage system in the new market-coordinated economy.
China shares with many other developing countries the characteristic of dual
economy. The rapidly growing modern capital-intensive sector is traditionally clustered
around the cities, while the traditional manual agriculture in the rural China remains
little changed. The coexisting modern industrial sector and backward agricultural sector
result in a large gap in income between rural and urban areas. For example, according to
State Statistical Bureau data, the income of the rural population was 1205 real yuan per
capita (base year ¼ 1995) in 1988, about 46% of the real 1988 urban income of 2552
yuan per capita. The gap has only widened over time with a rural average income in 1995
of 1578 yuan as compared 3893 yuan per capita in the urban areas (see Zhao, 2001). If
one considers only the coastal regions, which have received a higher priority in the
economic development, more economic freedom, and more financial assistance than the
provinces in inland China, these urban–rural differences would be even larger. Con-
sidering the uneven development throughout China, we restrict our study to urban areas
of China.
If we examine Taiwan’s post-war experience we find a similar level of economic
development as that of the late 1970s in China. The Taiwanese economy soared in the
1960s while at the same time income inequality dropped. Among those factors explaining
the Taiwan success story, labor absorption into non-agricultural sectors plays an important
role (see Kuo, Ranis, & Fei, 1981). Although the change in the wage structure of Taiwan is
not as dramatic as that of China, it did contribute toward lower income inequality in the
early years. Thus, at first glance Taiwan’s development path appears similar to that of
China in that urban areas absorb labor from agricultural sector so that the impact on
economy growth is quite similar; however, we note that development in China is occurring
with increasing income inequality.
The possibility of a shared development path, together with a common language and
culture suggest is useful to examine the determinants of earnings in Taiwan and China.
Data comparable to the People’s Republic of China for Taiwan (Survey of Personal
Income) is available beginning in 1979. To gain some further insight into the possibility of
a common development path, we provide separate earnings estimates for the most
developed part of the China, the southeastern coastal province of Guangdong.
The paper will proceed as follows. Section 2 describes the data and the changes in the
distribution of earnings that have occurred in Taiwan (1978–1995) and China (1988–1995)
over time. In order to better understand the similarities and differences between Taiwan and
China we estimate human capital models for both countries over time. It is widely
recognized that changes in returns to human capital can result in substantial changes
in earnings inequality and Section 3 presents the results of a Mincerian human capital
model. The final section provides some brief concluding remarks.

2. Earnings data for China and Taiwan
2.1. Data description
The data used in this analysis come from the Chinese Household Income Project (CHIP).
This longitudinal study has been created to examine the dimensions of inequality in China
and its’ causes. The data set consists of both samples of the urban and the rural populations
of China. Each of the component consists of two data files, one in which the individual is
the unit of analysis and a second in which the household is the unit of analysis.
The empirical analysis is based on the survey data collected in 1988, during the period of
the stalled reforms when the economy was undergoing a comparatively high inflation, and
1995, when the pace of reform greatly accelerated after Deng Xiaoping’s famous south-
eastern tour and 14th Communist Party Congress in 1992. The availability of the data in
these two years allows us to examine the change in personal earnings determinations
accompanying the structural changes of the economy.
There are two prominent advantages of the CHIP data over alternative sources. First, the
survey is very comprehensive in the information provided on the respondent. Included in
the survey are questions concerning general demographic characteristics as well as income
and expenditure of individual/household. There are variables that indicate education, age,
gender, ethnicity and other personal characteristics. All types and sources of income and
expenditure information are collected. These types of questions are one of the reasons that
this data is excellent to use when evaluating wage differentials with respect to the change of
the economy.1
The second advantage of the CHIP data are the large sample sizes that comes from all
regions of China. The 1988 data contains 9009 urban households (with 31,827
individual members) in 10 provinces. The 1995 data contains 6931 urban households
(with 21,698 individual members) in 11 provinces (the original 10 plus Sichuan). We
restrict analysis to the urban sample for two reasons. First, the post-1988 reforms are
most pronounced in the urban areas. Second, many rural workers are farmers who do not
work for wages.
The data in this paper have been constrained to meet the following conditions: urban
individuals who were working at the time of the interview and aged between 20 and 59.
This creates a data set with 17,006 observations for 1988 and 10,846 observations for
1995, respectively. The urban sample distributed over Beijing and 10 of the country’s 30
provinces: Liaoning, Henan, Jiangsu, Anhui, Hubei, Guangdong, Shanxi, Gansu,
Yunnan, and Sichuan. Based on the geographical location and economic development,
they could be classified into four regions: Liaoning and Henan are in the northern region;
Jiansu and Guangdong are in the eastern and southern coastal regions, respectively;
Hubei and Anhui are in the central region and Shanxi, Gansu, Yunnan, and Sichuan are
in the western region.
1 There are two useful collections of papers using the CHIP data, The Distribution of Income in China, edited
by Griffin and Zhao (1993a, 1993b) and China’s Retreat from Equality, edited by Riskin, Zhao, and Li (2001a,
2001b). For a recent review of China’s Retreat, see Osterriech (2002).

Starting from 1964, the Directorate-General of Budget, Accounting, and Statistics
(DGBAS), Executive Yuan, published the official household income survey data of Taiwan
biannual. In 1970, this survey data became annual. Microdata are available since 1976. A
stratified two-stage sampling method has been adopted. As with the CHIP data, the Taiwan
survey data is large enough and very comprehensive. The sample rate was 0.3% for 1975–
1977 and it was raised to 0.4% for 1978–1983. However, the sample size was fixed to
16,434 households for 1984–1994. The data is comprehensive in that general demographic
characteristics of respondents are included. We employ the same restrictions on this data as
for the China data.
2.2. Earnings distributions
Fig. 1a–c present the earnings Lorenz curves and Gini coefficients for Taiwan,
Guangdong, and urban China. For Taiwan, the period 1978–1995 was a continuation
of its trend toward smaller Gini coefficients (i.e., lower inequality). By examining the
Gini coefficients, we observe that while 1978–1983 was a period of stable inequality, the
period 1983–1988 saw a substantial decline in the Gini from 0.2894 in 1983 to 0.2687 in
1988. Furthermore, earnings inequality continued to decline after 1988, with the 1995
Gini falling to 0.2570. Why has Taiwan’s earnings inequality continued to fall? Lin
and Chu (2000) and Bourguignon, Fournier, and Gurgand (2001) explain the greater
equality by greater equality in education and by greater labor market participation by
women.
Fig. 1b presents the earnings Lorenz curves and Gini coefficients for urban Guangdong
province. In 1988 Taiwan and Guangdong showed nearly an equal degree of inequality as
measured by the Gini coefficient. But while Taiwan experienced declining inequality,
Guangdong’s Gini rose from 0.2625 in 1988 to 0.2853 in 1995.
The most dramatic change in earnings inequality occurred in urban China (Fig. 1c).
Between 1988 and 1995 the earnings Gini rose from 0.2241 to 0.2799, a 25% increase in
inequality. Clearly, China’s move to an emerging market economy has been accompanied
by a nearly unprecedented increase in inequality; Gustafsson and Li (2001a, 2001b, p. 36)
suggest that among industrialized countries only the UK matches China’s magnitude of
increasing inequality.2
The debate regarding growing income inequality in China revolves around the question
of whether it is growth itself that caused the rise in income inequality or are a specific set of
policies or reforms to blame. Riskin, Zhao, and Li (2001a, 2001b) argue that it was not
growth per se but the reform policies, yet they recognize the interactions between the two.
Zhao (2001) argues that ‘‘disorder policies’’ that tolerate corruption, insider appropriation
of state assets, monopoly, and rent seeking have had an injurious effect on the distribution
of income.
2 The highly publicized increase in the U.S. Gini coefficient in the late 1970s was less than 10%, 0.39–0.42
(Bishop, Formby, & Smith, 1991). Deninger and Squire (1996) provide a comprehensive list of Gini coefficients.
The report Gini’s as larger as 0.62 (Brazil) and as small as 0.18 (Bulgaria). China and Taiwan fall in between
these two extremes.

3. Estimating returns to human capital
3.1. Summary statistics
Table 1 presents summary statistics for Taiwan, urban Guangdong Province, and urban
China. For Taiwan we consider four years of data, 1978, 1983, 1988, and 1995. For
Guangdong and China we consider 1988 and 1995. We provide summary data on workers’
age, schooling, gender, and earnings. The last two rows of Table 1 provide the CPI and
sample sizes.
The first row of Table 1 provides information on workers’ ages. In Taiwan we observe a
slightly U-shaped age profile, with average age beginning and ending at about 36 years but
dipping as low as 35 years in 1993. Urban Guangdong province shows the most rapid
increase in workers’ average age, rising by nearly 2 years from 37.5 years in 1988 to 39.4
years in 1995. In contrast, urban China shows the slowest increase in workers’ average age,
rising by 1.1 years from 37.6 years in 1988 to 38.7 years in 1995.
The second row of Table 1 provides workers’ average years of schooling. For Taiwan,
average years of schooling increased steadily from 9.5 years in 1978 to 11.7 years in 1995.
Surprisingly, Guangdong’s schooling closely matches Taiwan, rising from 10.5 years in
1988 to 11.7 years in 1995. Urban China’s average workers’ education grew quite rapidly
during the 1988–1995 period from 10.6 years in 1988 to 12.0 years in 1995. In fact, the
average education level in urban China actually exceeds Taiwan’s in 1995.3
Rows 3 and 4 of Table 1 provide more detail on changes in worker education by
examining the percent of workers with high school and college degrees. By 1995 we find a

3 How do these education and aging trends impact inequality? Lin and Chu (2000) note that rising education
levels in Taiwan are associated with greater inequality. Bishop, Formby, and Smith (1992) find that U.S. states
with higher education levels tend to have more unequal distributions. Greater inequality may be generated as
some are left behind with low education. Bishop et al. also find that population aging is associated with greater
inequality.
554 J.A. Bishop, J.-R. Chiou / Journal of Asian Economics 15 (2004) 549–562
higher percentage of high school graduates in Guangdong (66.1%) and China (66.8%) than
in Taiwan (62.7%). However, Taiwan’s percentage of college graduates (12.3%) is
significantly higher in 1995 than either Guangdong (7.4%) or China (8.5%).
Rows 5–8 focus on differences in labor market participation and earnings by gender. We
find a steady decline in the percentage of Taiwanese workers who are male, falling from
72.3% in 1978 to 59.6% in 1995. In Guangdong and urban China as a whole the percent
male is only slightly above 50% in both years. Real male earnings (row 6) in Taiwan grew
by 230% between 1978 (11,377 NTD) and 1995 (37,527 NTD), while real Taiwanese
female earnings (row 7) grew by about 250% (7060 NTD to 24,579 NTD) over the same
time period.
Focusing on the 1988–1995 time period we find that real male earnings in Taiwan grew
by 44%, while real female earnings grew by 54%. For urban Guangdong, real male
earnings grew from 526 RMB in 1988 to 999 RMB in 1995, or 90%. For females in
Guangdong, earnings grew by 92% from 437 RMB to 840 RMB. Finally, for urban China
male earnings grew from 371 RMB to 559 RMB, or more than 50%. Female wages in
China grew by 49% between 1988 and 1995 from 312 RMB to 465 RMB.4
The male–female earnings ratio is given in row 8. For Taiwan, the decade between 1978
and 1988 shows very little change in the male–female earnings ratio (1.61 in 1978 and 1.63
in 1988); however, the relative earnings of females did increase between 1988 and 1995. As
expected the male–female earnings ratio is significantly smaller in both Guangdong and all
of urban China. For both Guangdong and urban China, male earnings exceed female
earnings by approximately 20%. How do these earnings gaps compare internationally?
Estimates provided by Waldfogel (1998) place China’s earnings gap in line with the
Scandinavian countries; Taiwan’s earnings gap is slightly larger than that in the U.S. but
significantly smaller than Japan’s.
It is interesting to note that the unadjusted earnings gap in China did not change between
1988 and 1995 even as China moved to a more market-oriented economy with greater
earnings inequality.5 In the next section we examine trends in returns to education,
experience and gender as possible explanations for changing levels of earnings inequality.
3.2. Earnings equations results
Table 2 presents the results for human capital regression models for earnings.6 Table 2a
proxies human capital with years of experience, experience squared, schooling and an
indicator for female and a female � years of schooling interaction term. Table 2b replaces
years of schooling with indicator variables for the various levels of schooling. Table 2a
includes results for Taiwan, 1978, 1983, 1988, and 1995, Guangdong, 1988 and 1995, and
all of urban China, 1988 and 1995. Table 2b excludes results from Guangdong province due
4 See Khan and Riskin (2001) (Table 2.2), for changes in price level in China.5 We note that Blau and Kahn (1996) attribute much of the gender earnings gap in the U.S. (relative to other
developed countries) to the high level of U.S. wage inequality.6 For other examples of earnings equations using the CHIP data see, Xie and Hannum (1996), Knight and
Song (1993, 2001), and Gustafsson and Li (2001a, 2001b). For a study of earnings in Taiwan, see Lin and Chu
(2000) and Bourguignon et al. (2001).

to small sample sizes in some of the education cells. As is typical in Mincerian earnings
models the dependent variable is the log of earnings.
Rows 2 and 3 of Table 2a provide the experience coefficients. We find very stable
experience coefficients in Taiwan, ranging between 0.057 and 0.062. Guangdong’s return
to experience in 1988 is very similar to Taiwan (0.056) and all of urban China shows
somewhat lower returns to experience in 1988 (0.049). However, both Guangdong and
urban China show declines in the return to experience over time. This suggests that the
skills that older workers acquired in a socialist economy have declined in value during the
transition to a more market-oriented labor market.
Fig. 2 plots the returns to experience for Taiwan, Guangdong, and urban China for 1988
and 1995. As expected each profile shows diminishing returns to additional years of
experience. In the case of Taiwan and Guangdong 1988 we find that earnings decline for
older workers with more than 25–30 years of experience. Examining the experience
profiles for China, we find a uniform decline in experience over time. While returns to
experience clearly decline in urban China between 1988 and 1995, this decline is most
dramatic in Guangdong. This is illustrated in Fig. 2 by the abrupt downward shift in returns
to experience in Guangdong between 1988 and 1995.
Row 4 provides the years of schooling coefficient for males. For Taiwan, this male
schooling coefficient is remarkably stable over time, ranging between 0.063 and 0.067. We
note that this is very close to the consensus estimate for the U.S. (cf. Krueger and Lindahl,
2001). While in 1988 the education coefficients for both urban Guangdong and urban
China are much smaller than in Taiwan, the returns to male education increased sharply
between 1988 and 1995 as the Chinese market economy emerged. For Guangdong, the
schooling coefficient increased from 0.029 to 0.047 and for China the schooling coefficient
increased from 0.028 to 0.056. To put rapid increase in the return to education in
perspective, in 1988 the male return to schooling in China was only 44% of that of
Taiwan, but by 1995 China’s return to schooling had grown to almost 90% of that of
Taiwan.

In order to control for differences in return to education by gender we interact female
with schooling (row 5). In all cases the interaction coefficient is positive, implying that in
Taiwan, urban China, and Guangdong returns to schooling are higher for females than for
males. In 1988 Taiwanese females earned 9.4% (6.3% þ 3.1%) per year of schooling, while
their Chinese counterparts earned 7.1% (2.8% þ 2.4%) per year of schooling. By 1995, the
return to schooling for Chinese females had grown to 8.8% or 95% of the return earned by
Taiwanese women.
Row 6 provides the coefficients for the female indicator variable. Together with the
female � schooling interaction term (row 3) we can obtain an estimate how the female
earnings penalty that varies with years of schooling. For example, the 1995 female
coefficient in Taiwan is �0.772, but as females earn higher returns to education this
penalty only directly applies to females without any schooling. Fig. 3 plots the female
penalty for Taiwan 1978 and 1995 and China 1988 and 1995. Recall from Table 1 that the
unadjusted earnings penalties for females are approximately 20% in China and 60% in
Taiwan. Fig. 3 shows that these penalties clearly vary with the level of education, with
lower educated females suffering larger earnings penalties that higher educated women. In
fact, we find little or no earnings penalty for college-educated Chinese women in both 1988
and 1995. Over time we find a decline in the Chinese female earnings penalty. In contrast,
in Taiwan lower educated women enjoy declining penalties over time while there is a small
increase in the earnings penalty for the most educated women.
Table 2b provides the model coefficients for a set of educational indicator variables. The
female interaction coefficient measures the additional educational premium earned by
females. In parentheses below the coefficient value is the percentage premium above the
omitted primary education level.7 For females this is the combined or total effect. We
exclude the Guangdong only sample from this table due to small sample sizes in some
education classes.
Fig. 4a and b plot the male and female education premiums for Taiwan and China. We
plot only one year (1995) for Taiwanese males as we find relatively little change in the
education premiums over time. The earnings benefits of education are higher in Taiwan at
every educational class than in China. However, between 1988 and 1995 China shows a
dramatic increase in the benefits of education. For example, returns to college to males
more than double from 36% in 1988 to 81% in 1995. Over time the returns to the different

levels of education in China have become very close to those in Taiwan, with the notable
exception of college.
Fig. 4b shows the female education premiums. As expected the female education
premiums are significantly larger than the male education premiums for each country and
each year. A rapid increase of the Chinese female education premiums together with a
small decline in its Taiwanese counterpart leads to nearly identical returns to education in
both countries, again with the notable exception of college.

4. Conclusion
In this paper we study labor market earnings for Taiwan and China to investigate the
possibility of a shared development path. To gain some further insight into the possibility of
a common development path, we provide separate earnings estimates for the most
developed part of the China, the southeastern coastal province of Guangdong. The data
for our study comes from the Taiwan Survey of Personal Income Distribution (1978, 1983,
1988, and 1995) and the Chinese Household Income Project (1988 and 1995). During this
time period China’s economy experienced a dramatic shift from a planned socialist
economy to an emerging market economy.
We find that earnings inequality continued to decline in Taiwan in the 1980s and
early 1990s. In contrast, the urban China earnings Gini coefficient increased by nearly
25% between 1988 and 1995. Likewise, Guangdong Province experienced an increase
in earnings inequality; in 1988 Guangdong had an earnings Gini very similar to
Taiwan, but by 1995 its earnings Gini was more than 10% larger than Taiwan’s. While
China’s rapid growth rates that occurred after economic liberalization appear to be
similar to those that Taiwan enjoyed during its emergence as a modern economy, the
initial conditions (i.e., China’s planned economy) were quite different. Thus, unlike
Taiwan, China’s economic development has not been accompanied by declining
inequality.
Between 1988 and 1995 Taiwan and all of urban China both experienced a nearly 50%
increase in real earnings. In contrast, urban Guangdong Province enjoyed a near
doubling of earnings. Average levels of education are similar in all three regions for
both years. In fact, China’s average level of education in 1995 actually exceeds that of
Taiwan; however, Taiwan has 50% more college graduates. All three regions show signs
of aging populations.
To help better understand these changes in earnings and inequality we examined
changes in the returns to human capital. For Taiwan, we find that male returns to
education are stable over time and closely approximate those in the United States. In
addition, we find stable returns to experience. We do, however, find falling female
penalties at the bottom of the education scale, which together with a slight increase in
the earnings penalty among higher educated women, is consistent with Taiwan’s
declining earnings inequality.
For China, we find surprisingly little difference between the human capital estimates
for all of China and the most developed part, Guangdong. Our findings show rapidly
rising returns to education in China and declining returns to experience. These findings
are consistent with an environment of rising earnings inequality between 1988 and
1995.
As expected, we find that the ratio of male to female earnings in China is much lower
than in Taiwan. We find that the shift from a planned economy to an emerging market
economy, with its greater degree of wage inequality, has resulted in a deterioration of
Chinese women’s relative earnings for all but college-educated women. Thus, a decline in
the Taiwanese female earnings penalty at most education levels combined with rising
female earnings penalties in China has resulted in a narrowing of the gap between relative
female earnings in the two countries.
560 J.A. Bishop, J.-R. Chiou / Journal of Asian Economics 15 (2004) 549–562
In sum, in spite of differences in the trend in earnings inequality, we find converging
levels and returns to education between the two countries. In contrast, returns to experience
appear not to be converging, most likely due to China’s dramatic economic restructuring.
