Study On The Temporal And Spatial Evolution Of Agricultural Science And Technology Service Efficiency Of Local Science And Technology Association

Agricultural science and technology services are the basic measures to accelerate agricultural modernization,promote the structural reform of the agricultural supply side,and realize quality agriculture and green development.In recent years,local science and technology associations have gradually created an all-round,multi-level,three-dimensional agricultural science and technology service system relying on grassroots organizations at all levels,which has become an important force in agricultural science and technology services,and has played an important role in achieving agricultural strength,rural beauty,and peasant wealth.This paper defines the core concepts related to the spatial and temporal evolution of agricultural science and technology service efficiency of local science associations,and constructs the evaluation index system of agricultural science and technology service input-output efficiency of local science associations based on public service theory,technology diffusion theory,efficiency theory and new regionalism theory.Measure and analyze the efficiency of agricultural science and technology services of local science associations in 31 provinces(municipalities and autonomous regions)in China from 2008 to 2016 with the efficiency DEA model,build the ESDA model and the ROOK first-order neighbor weight matrix,analyze the spatial correlation of the local science and technology association's agricultural science and technology service efficiency in the global and local dimensions,and explores the spatial and temporal evolution pattern of the local science and technology association's agricultural science and technology service efficiency.The results show that from 2008 to 2016,the average efficiency of agricultural science and technology service is between 0.793 and 1.360,showing a volatility trend as a whole,and the difference between the provinces and the eastern,central and western regions is significant.The average efficiency of agricultural science and technology services of the local associations in the eastern,central and western regions of 2008-2016 was 0.990,0.711 and 1.190 respectively,showing the pattern of'east and west high,central collapse'.The provinces with high efficiency of agricultural science and technology services are mostly distributed in the western regions with strong central government support and the economically developed eastern regions.The provinces with low efficiency of agricultural science and technology services are mostly distributed in the central regions with less central government support and low economic development level.The overall spatial correlation of the service efficiency has shown a downward trend,but many provinces have significant positive autocorrelation in the local geographic space.Therefore,strategies should be adopted to optimize the input structure,improve service levels,strengthen performance management,and coordinate regional development,and continuously improve the efficiency of agricultural science and technology services of local science associations.
