成渝城市群农业绿色生产率及空间效应研究

Study on Agricultural Green Productivity and Spatial Effect of Chengdu Chongqing Urban Agglomeration

提高农业绿色生产效率是保证生态优先和粮食安全的有效路径。本文运用非期望产出的SBM模型和空间计量方法探析成渝城市群农业绿色生产效率及其空间效应。分析发现:成渝城市群农业绿色生产效率呈稳步上升态势;农业绿色生产效率表现出较明显的空间相关性,农村经济发展水平提高、逐渐缩小的城乡收入差距以及农业产业结构调整是提高农业绿色生产效率的主要动力;因此,加强地区间农业生产互动,大力引导多元主体共同参与农业绿色生产,重视农业科技成果转化应用,是可持续提升农业绿色生产效率的关键。

Improving agricultural green production efficiency is an effective way to ensure ecological priority and food security.This paper analyzes the agricultural green production efficiency and its spatial effect of Chengdu Chongqing Urban Agglomeration by using the SBM model of unexpected output and spatial measurement method.It is found that the agricultural green production efficiency of Chengdu Chongqing urban agglomeration is rising steadily;Agricultural green production efficiency shows obvious spatial correlation.The improvement of rural economic development level,the narrowing income gap between urban and rural areas and the adjustment of agricultural industrial structure are the main driving forces to improve agricultural green production efficiency;Therefore,strengthening the interaction of agricultural production among regions,vigorously guiding multiple subjects to participate in agricultural green production,and paying attention to the transformation and application of agricultural scientific and technological achievements are the key to continuously improve the efficiency of agricultural green production.
