Abstract

Abstract:

【Objective】 Improving agricultural green total factor productivity (GTFP) helps to promote green agriculture development. 【Methods】 This study uses panel data from Xinjiang Uygur Autonomous Region and Xinjiang Production and Construction Corps from 2012 to 2021, and applies the SBM-GML model to measure agricultural green total factor productivity (GTFP), green technology efficiency (GEC) and green technology progress rate (GTC), and measures their spatial correlation with the global Moran index. 【Results】 (1) The green total factor productivity (GTFP) and green technology progress rate of Xinjiang agriculture show an overall increasing trend, but the green technology efficiency shows a decreasing trend.(2) There is some spatial variability in the green total factor productivity of Xinjiang agriculture, and the overall distribution is characterized by “high in the south and low in the north”.(3) Except for some prefecture-level administrative regions, the spatial correlation of green total factor productivity in Xinjiang agriculture is not significant. 【Conclusion】 We should prioritize the development of green technological progress efficiency in Xinjiang agriculture, promote the development of green total factor productivity in agriculture, and promote the high-quality green development of agriculture according to local conditions.

摘要：

【目的】 提高农业绿色全要素生产率(GTFP)有助于促进绿色农业发展。【方法】 采集新疆维吾尔自治区和新疆生产建设兵团2012~2021年面板数据,运用SBM-GML模型测算农业绿色全要素生产率(GTFP)、绿色技术效率(GEC)和绿色技术进步率(GTC),并用全局莫兰指数衡量其空间关联性。【结果】 (1)新疆农业绿色全要素生产率和绿色技术进步率总体呈上升趋势,但绿色技术效率呈降低趋势。(2)新疆农业绿色全要素生产率存在一定的空间差异性,总体呈出“南高北低”的分布特点。(3)除个别地级行政区,新疆农业绿色全要素生产率的空间关联性不显著。【结论】 应从优先发展新疆农业绿色技术进步效率开始,促进农业绿色全要素生产率发展,因地制宜,推动农业高质量绿色发展。
