Human capital The knowledge, skills, competencies and attributes embodied in individuals that facilitate the creation of personal, social and economic well-being --OECD, 2001 Importance of Human Capital A central determinant of economic growth Significant contributions to 30 years economic growth in China Enhances the ability in Developing technological innovations Adapting and implementing technologies developed Reduce poverty and inequality 2 China Center for Human Capital and Labor Market Research

Human capital Importance of Human Capital Measurement Trace the distribution and dynamics of human capital Aid empirical studies and policy analysis Promote the creation of human capital satellite account 3 China Center for Human Capital and Labor Market Research

Human capital measurement Challenges The unique characteristics make it difficult to estimate its value Partial measurements like education are commonly used Lack of data existing method cannot be applied to China Arduous work for data collection, processing and calculation, especially at provincial level Empirical researches desire panel data of human capital o Panel data of comprehensive measures of human capital at a state or province level are lacking for most countries including China 4 China Center for Human Capital and Labor Market Research

Methodology Jorgenson-Fraumeni Lifetime Income-based Approach Include all aspects of human capital services measured by market value Widely used in measuring a nations total human capital stock Argentina (Coremberg, 2010), Australia (Wei, 2007, 2008), Canada (Gu and Wong, 2009), India (Gundimeda et al., 2007), New Zealand (Le, Gibson, and Oxley, 2005), Norway (Liu and Greaker, 2009), Sweden (Ahlroth, Bjorkland, and Forslund, 1997), United Kingdom (OMahony and Stevens, 2004 and Jones and Chirpanhura, 2010), and the United States (Christian, 2010) The OECD human capital consortium OECD, 2010; Mira and Liu, 2010; Liu, 2011 Chinas national level human capital Li et al., 2010; Li, Liang et al., 2013 6 China Center for Human Capital and Labor Market Research

Methodology Jorgenson-Fraumeni lifetime income-based approach Calculate human capital stock for each individual as the estimated present value of expected future lifetime earnings Backward recursive estimation beginning with the oldest covered age Divide life cycle into five stages Retirement, Work-only, Work-school, School-only, Pre-school Modifications Incorporate the Mincer model (National level) Expand Mincer model to include macro-variables (Provincial level) Derive total human capital stock separated by urban and rural in estimation Adjustment for cross-province comparison with a living cost adjustment index 7 China Center for Human Capital and Labor Market Research

Augmented Mincer model Lack of data in China use the Mincer model to estimate earnings Extended model for earnings in provinces ln(inc)= 0 + 1 ln(Avwage)+ 2 Sch+ 3 Sch Avgdp+ 4 Sch Ratio+ 5 Exp+ 6 Exp 2 +u ln(inc): the logarithm of earnings Sch: years of schooling Exp: years of work experience Avwage: average wage of a province Avgdp: provincial GDP per capita Ratio: provincial primary industry employment proportion of the total labor force u: random error 8 China Center for Human Capital and Labor Market Research

Augmented Mincer model Extended model Avwage reflects the income gap among provinces Reflect provincial differences in earnings of those with no schooling and no labor-market experience Avgdp and Ratio capture the provincial economic development stage and labor market structure Return to schooling is affected by the development stage and labor market structure (Li 2003, Zhang et al., 2005, and Yang, 2005) 9 China Center for Human Capital and Labor Market Research

Human capital and physical capital LFHC/physical capital Decreases rapidly across time 12 times in 1985 5 times in 2010 Possible reason: High physical capital investment in China Increased at an average annual growth of 18.9% during 1992- 1997 32 China Center for Human Capital and Labor Market Research

Human capital and GDP GDP/LFHC Measure of labor use efficiency Provincial ratio is between 6-11% on average Shows a slow and stable growth Compared with GDP/physical capital: In the range of 49-66% Decline since 1995 Human capital rises faster than physical capital in efficiency 33 China Center for Human Capital and Labor Market Research

Summary The data provide very rich information in studying Chinas human capital A comprehensive picture of Chinas human capital distribution and dynamics Demonstrations of applications of the new data Estimating a production function Conducting the growth decomposition exercise using the data Compared the results with the traditional estimation based on labor inputs The new panel data on Chinas provincial human capital are quite reliable; and should be a valuable new resource for related studies and policy analysis 40 China Center for Human Capital and Labor Market Research
