摘要
畜牧业绿色全要素生产率提升既关系着畜牧养殖业长远发展,也是影响畜牧业整体竞争力稳步提高的关键。为探析我国畜牧业绿色全要素生产率的集聚演变及影响因素,文章采用重心模型、动态空间杜宾模型对2000—2023年我国30个省份的畜牧业绿色全要素生产率展开测算及分析。结果显示,我国畜牧业绿色全要素生产率存在空间聚集现象,莫兰指数整体呈“先降再升再降再升”的态势。生产重心演变轨迹结果显示,我国各地区畜牧业绿色全要素生产率重心呈“先东北后西北、西南”的演变态势。机制检验表明,环境规制水平、畜牧业产业集聚、绿色信贷、城镇化水平、财政支农水平是促进畜牧业绿色全要素生产率提升的关键因素。研究表明,我国畜牧业绿色全要素生产率整体呈现“先降再升再降再升”空间演变与“先东北后西北、西南”的区位重心演变趋势,且主要受到环境规制水平、畜牧业产业集聚、绿色信贷、城镇化水平、财政支农水平因素影响。
The improvement of green total factor productivity in animal husbandry is not only related to the long-term development of animal husbandry,but also a key factor in the steady improvement of the overall competitiveness of the industry.In order to analyze the agglomeration evolution and influencing factors of green total factor productivity in animal husbandry in our country,this paper calculates and analyzes the green total factor productivity in animal husbandry in 30 provinces from 2000 to 2023 by using the gravity model and dynamic spatial Dubin model.The results show that there is a spatial aggregation phenomenon in green total factor productivity of Chinese animal husbandry,and the Moran index of green total factor productivity assumes the trend of 'decreasing,then increasing,then decreasing again,and then increasing again.' The results of the evolution of the production center show that the green total factor productivity center of the animal husbandry in different regions of our country is evolving from northeast to northwest and southwest.Mechanism testing shows that the level of environmental regulation,agglomeration of animal husbandry industry,green credit,urbanization level,and fiscal support for agriculture are key factors in promoting the improvement of green total factor productivity in animal husbandry.The study indicates that the overall green total factor productivity of Chinese animal husbandry industry shows a spatial evolution trend of 'first decreasing,then increasing,then decreasing,and then increasing',as well as a regional center evolution trend of 'first northeast,then northwest,and southwest',and is mainly influenced by factors such as environmental regulation level,animal husbandry industry agglomeration,green credit,urbanization level,and fiscal support for agriculture.
