准市场型农业社会化服务效率测定及驱动因素分析
[Abstract]:The extensive development of traditional agriculture in our country has caused the environmental pollution problem to become more and more prominent. In the process of modern agriculture development, the rural ecological environment problem has not been well contained. Since agricultural production is facing the double squeezing of resources and environment, it is worth further study to establish an agricultural service system which takes into account the economic, ecological and social benefits. In this paper, provincial panel data from 2008 to 2015 are used to determine the efficiency and decomposition factors of socialized service of quasi-market agriculture. Then, the formation mechanism of agricultural socialized service and the economic analysis of agricultural service are discussed in theory. The article holds that the main body of new grain management, such as professional large households, family farms, cooperatives and agricultural enterprises, not only plays the role of service provider, but also plays the role of agricultural technology dissemination intermediary. However, technological progress and transaction costs are the key factors restricting the development of agricultural services. Then it analyzes the difference of service efficiency of quasi-market agriculture socialization, including the difference of service efficiency in grain function area. In addition, the paper discusses the spatial effect of the development of the socialized service technology of quasi-market agriculture. Finally, the driving factors of efficiency in 2008 ~ 2015 are analyzed and discussed. The main conclusions are as follows: (1) the socialized service efficiency of quasi-market-oriented agriculture in China is in a steady state, and the sustained stability of technological progress is the main reason for this phenomenon. The efficiency of socialized service of quasi-market agriculture declined significantly in 2013 and 2014. The outburst period of growth was in the period of 2008 ~ 2009, and 26 provinces were in the trend of fast and positive growth. Based on the overall time trend, based on 2008, the quasi-market-oriented socialized service efficiency index in most regions shows a trend of steady and deep V rebound after a decline. (2) in the region, The overall service efficiency of quasi-market-oriented agriculture socialization in the central region has great advantages, but in terms of technological progress, The eastern region maintains an absolute lead. (3) the gap between individuals of quasi-market-oriented socialized service efficiency in each grain function area is gradually narrowing. The overall efficiency value is on the rise. (4) there is a positive spatial correlation between the development of quasi-market-oriented socialized service technology in the provinces and regions of China. That is, the phenomenon of spatial convergence exists. (5) the construction of agricultural mechanization plays an irreplaceable role in driving the socialized service efficiency of quasi-market-oriented agriculture, while the efficiency of quasi-market-oriented agricultural socialized service is of chemical fertilizer. Dependence on pesticides is decreasing.
