Abstract

In recent years, various factors such as policies to promote the role of China's agricultural production for five consecutive years to achieve substantial grain, structural adjustment is gradually advancing. But over the years, technical progress is factor inputs rather than support the fundamental elements of China's agricultural growth has not been fundamentally changed this situation. By measuring the level of inter-provincial agricultural productivity growth seen in recent years is caused by technical regress in agricultural productivity tends to decline in China's root causes. On the other hand, quantitative study of the structural changes affecting agricultural productivity factors found that some level of agricultural productivity to improve the policy, from a practical point of view has not been able to achieve the original intention of the policy, it is necessary to make appropriate amendments. China has achieved great increases in agriculture by various factors such as policies, especially the policy of structural adjustment in recently years. However, it is the factor inputs rather than technical progress which supports the growth of China's agriculture for a long time, and which has not been changed fundamentally. The level of agricultural productivity growth has been checked to find that the downward trends of agricultural productivity has been mainly caused by technical regression. At the same time, some policies which aimed at enhancing agricultural productivity didn't achieve the target which is necessary to make some amendments
