The Comparative Study On Agricultural Support Policies Among China And Main Developed Countries

China has seen rapid economic growth since 30 years of Reform and Opening-up. At the same time, however, the income gap between urban and rural residents has been widened and agricultural competition and rural development has been lagged behind significantly. To reverse this situation, since the year 2004, Chinese government has launched support policy to farmers for planting grain, and balanced urban and rural development. The history for Chinese implementation of agricultural support policy is short. The method for current agricultural support is simple and the efficiency of support policy appears to be slowing down. However, most of the major developed countries have decades of history for implementation of agricultural support policies. Therefore, the author mainly compares agricultural support policies among China and main developed countries, and puts forward some suggestions to optimize the Chinese agricultural support mode, formulate reasonable agricultural support level, and improve the efficiency of agricultural support policy implementation.The study firstly classified the evolution of agricultural support policy in OECD member countries, and selected comparative countries with China from the evolution's type. Secondly, the author took historical and logical analysis methods to analyze the purpose and measures of implementing agricultural policies among China and main countries in different stages of development. Thirdly, the author adopted quantitative and qualitative analysis method to analyze main factors contributed to the level of agricultural support among China and main developed countries. Fourthly, through the comparison performances of the agricultural support policies among China and main developed countries, as well as the cause analysis for high performance of agricultural support policy, the author put forward some suggestions to improve the performance of Chinese agricultural support policy.The conclusion of the paper indicates that: First, current the evolution of agricultural support policies of main developed countries can be divided into four types, and comparison countries the author selected includes the United States, the European Union and South Korea. Secondly, although the purposes for implementation of agricultural support policies among China and main developed countries are different, the method of agricultural support transferring from agricultural price support to income directly support is the direction of agricultural support policies adjustment in WTO member countries. Thirdly, the main influence factors contributed to the level of agricultural support policies are different in the countries with different economic development level. Fourthly, the order of performance level on agricultural support policy from high to low is United States, China, South Korea and European Union.In order to optimize and improve the performance of Chinese agricultural support policy, the author puts forward five pieces of suggestions. Firstly, according to the changes of international and domestic environment, we should define the purpose and optimize measure of our agricultural support policy. Secondly, based on the important influential factors to the level of Chinese agricultural support, we can practice reasonable level of agricultural support. Thirdly, strengthen general services support to Chinese agriculture. Fourthly, improve the matching mechanism of agricultural support policy. Fifthly, strengthen legalization construction on agricultural support policy.The main features and innovations of this paper are as following. Firstly, the author used system clustering analysis method to classify the evolution of agricultural support policies of OECD number countries. Secondly, adopting OECD's agricultural policy evaluation system, the author analyzed the purposes and main measures of agricultural support policies among China and main developed countries. Thirdly, using multiple linear regression model, the author analyzed the influential factors to the level of agricultural support among China and main developed countries. Fourthly, using the data envelopment analysis, the author compared the performance of agricultural support policies among China and main developed countries.
