Introduction China has achieved significant economic growth since the Reform and Opening Policy in
1978.
- The annual GDP growth rate on average had been more than 10% for the past 20 years.
- In 2010 China had been the second largest economy in the world with a GDP of US $5.8 trillion
after the United States.
However, China’s health care system did not match this rapid economic development
during the same period.
- It is hard to receive health care services.
- The health care is relatively expensive.
- 3 -
Introduction (continued) To bridge this gap, China has substantially reformed its health care system in recent years.
The ultimate goal is to provide universal coverage for basic health care to every Chinese
citizen.
Three major health insurance plans have recently been created to achieve this objective.
- Rural newly cooperative medical scheme.
- Urban employee-based health insurance.
- Urban resident health insurance.
- 4 -
Introduction (continued) By the end of 2009, these three major health insurance plans covered approximately 90
percent of the Chinese population (1.2 billion Chinese citizens).
The three major health insurance plans differ substantially in terms of insurers, the insured
population, premiums, and benefits offered.
One concern is that individuals under the different health insurance plans may vary their
health seeking behaviors.
The present study is trying to investigate whether three different health insurance plans
create disparities in terms of health care utilization and expenditures.

Rural newly cooperative medical scheme The cooperative medical scheme was initially implemented in rural China in the 1950s.
The old cooperative medical scheme was financed by the rural collective economy, and one
village clinic provided health care services to all the residents in the village.
Due to collapse of the rural collective economy, the old cooperative medical scheme was
nearly bankrupted in the 1980s.
- 7 -
Rural newly cooperative medical scheme (continued) In 2003, the rural newly cooperative medical scheme was launched.
- Participation is voluntary but at the household level.
- County-level administration is required.
- Its coverage focuses on catastrophic illness for inpatient and outpatient services.
- Some general outpatient health care services and basic preventive care are not included, such as
annual physical exam.
Government subsidies are the major financial contributions to this plan, and individual
premiums are very low.
In 2012, the rural newly cooperative medical scheme covered nearly every rural resident in
China.
- 8 -
Urban employee-based health insurance
With the rapid growth of foreign investment enterprises and bankruptcies of state-owned
and collective economies in urban China, employee-based health insurance was needed in
the early 1990s.
In 1998, urban employee-based health insurance was officially launched to insure urban
working population.
This plan intended to replace the so called “free health insurance” provided by the
state-owned and collective enterprises.
- 9 -
Urban employee-based health insurance (continued) Both employers and employees need to contribute approximately 6 percent and 2 percent,
respectively, of employees’ annual wages to the plan.
Government subsides are limited.
Its coverage is more comprehensive than the other two major health insurance plans due to
its higher premium contributions.
The coverage is only for employees, and other family members in urban China are not
insured.
- 10 -
Urban resident health insurance In 2007, China launched a new health insurance plan to insure non-employed urban
residents.
Young children, students, and other non-employed residents in urban China were covered.
Prior to 2007, health care costs were paid for completely out-of-pocket.
Government subsidies are also the major financial contributions to this plan, and individual
premiums are very low.
It is similar to the rural newly cooperative medical scheme in terms of coverage benefits.

Data This study uses data from the China Health and Nutrition Survey (CHNS) 2009 maintained
at the Carolina Population Center in the United States.
The CHNS covers nine provinces (Heilongjiang, Liaoning, Jiangsu, Shandong, Henan,
Hubei, Hunan, Guangxi, and Guizhou) in China that differ substantially in terms of
economic development, public resources, and health care indicators.

Data (continued) Key variables in the study:
- Health insurance plans.
- Health utilization.
- Health expenditures.
Control variables in the multivariate regression include provinces, gender, age, race
minority, marital status, education levels, employment status, occupations if currently be
working, household income, household size, urban location, chronic/acute diseases
previously diagnosed, and survey months.
After omitting some respondents with missing values for above key variables, our final
study sample includes 9429 adult respondents aged 18 and above.
- 15 -
Health insurance variables Each adult in the CHNS 2009 is asked whether he or she has health insurance at the survey
time.
If the answer is yes, he or she is asked to report the specific health insurance plan.
Three binary variables are created to represent each major health insurance plan with the
rural newly cooperative medical scheme as the reference group (the most common health
insurance plan).
We also add a binary variable indicating no health insurance.
- 16 -
Health utilization variables Preventive health care services (a binary measure).
- Each adult in the CHNS 2009 is asked “During the past 4 weeks, did you receive any preventive
health care services, such as health examination, eye examination, blood test, blood pressure
screening, tumor screening?
- The first health utilization variable measures whether the respondent receives preventive health
care services.
- 17 -
Health utilization variables (continued)
Seeing a doctor for illness (a binary measure).
- Each adult in the CHNS 2009 is also asked “During the past 4 weeks, have you been sick/ injured?
Have you suffered from a chronic or acute disease?”
- If the answer to above question is yes, the respondent is further asked “What did you do when
you felt illness?” The potential answers include 1) seeing a doctor, 2) self care, and 3) doing
nothing.
- The second health utilization variable measures whether the respondent saw a doctor for illness.
- 18 -
Health expenditure variables Total health expenditures (a continuous measure).
- If the respondent saw a doctor for illness during the past 4 weeks, he or she was asked to report
the total health expenditures for this treatment.
Reimbursement percentage (a continuous measure).
- Then the respondent was further queried as to what percentage of these health expenditures had
been paid or might be paid by insurance if he or she had health insurance.

Methods Bivariate analysis:
- We compare health care utilization and expenditures among people with different health
insurance schemes using the Chi-square test for binary health utilization variables and the
Student’s t test for continuous health expenditure variables.
Multivariate analysis:
- Health utilization or expenditures are hypothesized to a function of health insurance plans,
provinces, and other control variables:
XPIH 3210
- Logistic regression for the binary measures of health utilization.
- Ordinary least squared regression for the continuous measures of health expenditures.

Conclusions We find substantial disparities in terms of receiving preventive health care services for the
different health insurance plans, but no evidence supports the existence of disparities when
people need to see a doctor for illness.
- One potential explanation is that the rural newly cooperative medical scheme and urban resident
health insurance may not cover all the general outpatient services and/or annual physical exams,
which often provide most preventive health care services.
Health insurance plans do not affect total medical expenditures, but urban employee-based
health insurance is significantly more generous in terms of reimbursement percentage.
- This disparity in reimbursement percentage may reflect more comprehensive benefits packages
in urban employee-based health insurance.
- 27 -
Conclusions (continued) Preventive health services have been shown to enhance health and reduce future medical
expenditures, so providing more preventive health services to people with the rural newly
cooperative medical scheme and urban resident health insurance are policy changes that
warrant serious consideration.
The ultimate goal in China’s health care reform is to provide universal coverage for basic
health care to every Chinese citizen, and policy makers may consider how to increase the
reimbursement percentages for those under the rural newly cooperative medical scheme
and urban resident health insurance.
