摘要
面源污染和碳排放阻碍我国农业绿色生产效率的提升,而农业绿色发展的实现与高效的农业绿色生产效率有关。基于面源污染和碳排放,构建农业绿色生产效率“经济能源环境社会”评价指标体系,以作为生态文明建设先行示范带的长江经济带2010—2019年农业面板数据为例,结合内在增长和外在驱动对效率提升路径进行研究。结果显示:研究期内长江经济带农业生态效率上中下游都主要呈现偏右“U”型变化,效率提升应从增加模式转化为优化模式;研究期内区域差异呈现“扩大-收敛”的变化特征,高效率地区呈现“点-片-点-片”的扩散作用,存在一定的涓滴效应;从内在增长方面需要注意水资源管理使用、环境治理、区域科技进步动力、区域合作链等因素的影响;外部驱动因素中城镇化程度、产业结构、科研水平与效率呈现正向显著关系,从业人员收入水平、粮食作物种植面积以及财政支持强度呈现负向显著关系,需关注环境规制的不显著结果。
The non-point source pollution and carbon emission hinder the improvement of green production efficiency of agriculture in China,and the promotion and realization of green development of agriculture is related to its high green production efficiency.Based on the non-point source pollution and carbon emission,an index system for economy-energy-environment-society of green production efficiency of agriculture is established.Taking the panel data of agriculture in the Yangtze River Economic Belt from 2010 to 2019 as the demonstration belt of ecological civilization construction as an example,the improvement paths of efficiency are studied by combining the internal growth and the external drive.The results show that during the study period,the eco-efficiency of agriculture in the upper,middle and lower reaches of the Yangtze River Economic Belt exhibits a U-shaped change to the right,and the efficiency improvement should be transformed from the increase mode to the optimization one.The regional differences are characterized by enlargement and convergence,and the high-efficiency areas indicate the effect of point-point-point-piece diffusion,with a certain trickle-down effect.In terms of the internal growth,attention should be paid to the influences of some factors including management and use of water resources,environmental governance,regional drive for scientific and technological progress,and regional cooperation chain.Among the external driving factors,the urbanization degree,industrial structure,scientific research level and efficiency have a positive and significant relationship,while the income level of employees,planting area of food crops and financial support intensity have a negative and significant correlation.The insignificant results of environmental regulation need to be highlighted.
