Research On The Spatial Spillover Effects Of Agricultural Industrial Agglomeration On Green Total Factor Productivity Growth In The Context Of High-quality Development

Since the reform and opening up,China’s agricultural production has made great achievements,but also faces many development difficulties.The traditional "extensive" agricultural development model of high pollution and high consumption can no longer meet the requirements of sustainable agricultural development.Therefore,the 19 th National Congress of the Communist Party of China proposed high-quality development to promote various industries to achieve industrial transformation and achieve green development.In this context,promoting the green and high-quality development of agriculture has become a major issue that needs to be addressed mainly.Agricultural industrial agglomeration is an important thrust for green and high-quality agricultural development,and the growth of agricultural green total factor productivity(GTFP)is an important goal of green and high-quality agricultural development.Exploring the impact of agricultural industry agglomeration on the growth of agricultural GTFP will help to realize the green transformation and high-quality development of agriculture.In this paper,the theory of agricultural industry agglomeration and agricultural quality development,clarify the mechanism of agricultural industry agglomeration on agricultural GTFP growth,based on the location entropy method,evaluate the evaluation of the SBM agricultural GTFP,further construct the space Durbin model,empirical inspection of the space spillover effect of agricultural industry agglomeration on agricultural GTFP growth,and further divide China into north and south regions,testing the heterogeneity of the influence of agricultural industry agglomeration on agricultural GTFP.In addition,this paper also studies the spatial spillover effect of agricultural industrial agglomeration on the efficiency of agricultural green technology and the progress of agricultural green technology,and deeply discusses the action mechanism of agricultural industrial agglomeration on agricultural GTFP.The results indicate that:(1)China’s agricultural GTFP was improved overall during the inspection period.According to the analysis results of Moran index and Moran scatter plot,there is a significant spatial correlation between Chinese agricultural GTFP and presents the positive spillover effects of high-high and low-low.Specifically,the provinces with a high agricultural GTFP can drive the GTFP growth in the surrounding provinces,and vice versa.(2)From the regression results of spatial Durbin model,agricultural industry agglomeration promotes the growth of agricultural GTFP through significant positive direct effect and spatial spillover effect,that is,the growth of agricultural GTFP in the region is promoted by the positive effect of agricultural industry agglomeration in the region and surrounding areas.In addition,agricultural industrial structure,land use capacity and urbanization level have significant positive direct effects on agricultural GTFP,while agricultural support and rural electricity consumption per unit area have significant negative direct effects;rural electricity consumption per unit area,land use capacity and urbanization level have significant positive spatial spillover effects on agricultural GTFP.(3)There is a heterogeneity in the influence of agricultural industrial agglomeration on agricultural GTFP.Specifically,in the northern region,the neighboring agricultural industrial agglomeration suppresses the growth of agricultural GTFP,but the direct effect is not significant,while the agricultural industrial agglomeration in the southern region will significantly promote the growth of agricultural GTFP in the region,and the spatial spillover effect is not significant.(4)From the regression results of agricultural industrial agglomeration on agricultural green technology efficiency and agricultural technology progress,the improvement of agricultural industrial agglomeration in adjacent areas will inhibit the growth of agricultural green technology efficiency and further inhibit the growth of agricultural GTFP;while the local agricultural industrial agglomeration will promote the growth of agricultural green technology efficiency and further promote the growth of agricultural GTFP.
