Evaluation and Influence Factor of Green Efficiency of China's Agricultural Innovation from the Perspective of Technical Transformation

Agricultural innovation is important for the green transformation of agriculture. Based on the perspective of technology transformation, this paper builds a theoretical analysis framework and evaluation index system for green efficiency of agricultural innovation,and discusses the evolution laws and influencing factors of the green efficiency of China's agricultural innovation from 2005 to 2017 utilizing the DEA model, Malmquist index, and Tobit regression analysis. The results show that: 1) The overall green efficiency of China's agricultural innovation is not high, the green efficiency of agricultural innovation in eastern China is mainly driven by pure technical efficiency, while that in central and western China is mainly driven by the scale efficiency. The green efficiency of agricultural innovation shows significant spatial differences, and the low efficiency and relatively low-efficiency regions moved to central and southeastern China. 2) Technical progress is the main force affecting the change of green total factor productivity of China's agricultural innovation, seeing a trend of decrease followed by an increase. Pure technical efficiency and scale efficiency exhibit an increasing-decreasing trend, and gradually transform into key factors that restrict the improvement of the green total factor productivity of agricultural innovation. 3) Agricultural technologies' diffusion, absorption, and implementation are three influencing factors of the green efficiency of agricultural innovation. The local level of informatization, the number of agricultural technicians in enterprises and institutions, average education level of residents, and the level of agricultural mechanization have positive impacts on the promotion of the green efficiency of agricultural innovation, promoting the diffusion, absorption and implementation of agricultural innovation technology can significantly improve the green efficiency of agricultural innovation.

Characteristics and mechanism of agricultural transformation in typical rural areas of eastern China: A case study of Yucheng City,Shandong Province

Rural off-farm employment, rapid loss of agricultural land, and advanced technology popularization had led agricultural production in Chinese typical rural areas come at a critical transformation and upgrade stage. Based on sample survey data gathered from 401 households in Yucheng City, Shandong Province, this paper focuses on the characteristics and mechanism of agricultural transformation in typical rural areas of the eastern China. It was found that 74.3% of households surveyed kept at least one member engaging in off-farm employment, and 57.1% looked forward to expanding the operational scale of arable land, while just 13.7% had actually transferred their agricultural land. Since growing off-farm employment does not result in the collapse of traditional subsistence agriculture, therefore, agricultural production in Yucheng City is at an incomplete transformation phase from traditional small-holder farming to modern scale economy. It is caused by both macro environments and family characteristics, while urban-rural dual structure, imperfect rural development policy and agricultural technology popularization make peasant economy strengthen upon maintenance, and small-holder farming becomes peasant’s natural response owing to pluriactivity, local off-farm employment, reverse elimination, etc. In order to achieve smooth agricultural transformation of typical rural areas in the eastern China, it needs to promote professional differentiation among peasants, under clear policies adopted by central government. Providing comprehensive services for agricultural production and improving production skills and knowledge of farmers who are still living in the countryside will effectively stimulate the process of agricultural transformation.     

AN ASSESSMENT FOR SUSTAINABLE DEVELOPING CAPABILITY OF INTEGRATED AGRICULTURAL REGIONALIZATION IN CHINA

Based on the provincial units evaluation,this paper makes an assessment for sustainable developing capability of the integrated agricultural regionalization in China.At first ,an index system of agricultural sustainable development in China is built up,which includes 5 supporting subsystems of agricultural resources,agricultural develop-ment ,environment and ecosystem,rural society,sciences-esucation and management.We selected 95 factors on provin-cial level as basic indexes.Second,a relative assets/debt assessing method is used to gain relative net assets values (relative superiority) of every provincial unit,which are as supporting data for assessment.We also overlaid the Administra-tive Divisions Map of China and the Map of Integrated Agricultural Regionalization of China by Geography Information Sys-tem(GIS) to gain the area units of assessment.Third,according to the relative coherence principle of regionalization,we transform administration units to natural units through homogenizing all provincial relative net assets values in every agricultural assessing unit.After making order and grade,we complete the sustainable developing capability assessment to integrated agricultural regionalization in China.The assessing outcome shows that the total sustainable agricultural devdelop-ing capability of China is not high.Only about 1/3 in number or in area has reached the level of agricultural sustainable development.The relative net assets values exists a reducing trend from East China to West China.It needs a long period and great efforts to realize sustainable agricultural development over all China.Finally,there is a discussion to the study method.
