Abstract
In order to objectively analyze the developmental levels of agricultural modernization in major grain producing areas of China and their regional differences, by comparing with the latest domestic research results, we used principal component analysis combined with Hodrick-Prescott filtering to conduct an empirical study and make an objective evaluation of the levels of agricultural modernization effectiveness in major grain producing areas of China since the reform and opening-up (1978~2014). The research showed that the level of agricultural modernization effectiveness in a narrow sense was generally higher than that in a broad sense, which was consistent with the actual situation;the levels of agricultural modernization effectiveness in all major grain producing areas generally revealed a rising trend; the ranking of the levels of agricultural modernization effectiveness in different major grain producing areas changed dynamically , and their regional differences were shrunk gradually;in the earlier, middle and later periods of the reform and opening-up, the levels of agricultural modernization effectiveness in all major grain producing areas showed a rising, adjusting, and rising trend, respectively.In order to further promote the progress of agricultural modernization in China's major grain producing areas , we should continuously improve the efficiency of utilizing agricultural resources , transform the production and management patterns of agriculture , and expedite the conversion of agricultural scientific and technological a-chievements.关键词
