物流业绿色全要素生产率影响因素的时空异质性研究——基于中国八大经济区视角

Research on the Spatiotemporal Heterogeneity of Factors Affecting Green Total Factor Productivity in the Logistics Industry—A Perspective from China’s Eight Major Economic Zones

摘要: 文章使用2007~2021年中国30省份的数据，运用Super-SBM模型测算了八大经济区的物流业绿色全要素生产率；运用时空地理加权回归模型研究物流业绿色全要素生产率影响因素的时空异质性。结果表明：全国物流业绿色全要素生产率的整体水平逐渐提升，沿海地区的物流业绿色全要素生产率较高，而黄河中游、长江中游和西南地区的物流业绿色全要素生产率偏低；物流业绿色全要素生产率影响因素的作用机制具有显著的时空非平稳特征，不同时空节点下，各要素的作用方向及时变趋势均不同；城市化进展和交通网络密度对大部分地区的物流业绿色全要素生产率都有正向作用，其中交通网络密度对西南、西北等地形较为复杂的区域有负向作用，而能源消费强度对绝大部分地区都存在负向影响。

Abstract: The article uses data from 30 provinces in China from 2007 to 2021 and uses the Super SBM model to calculate the green total factor productivity of the logistics industry in eight major economic regions; Using a spatiotemporal geographically weighted regression model to study the spatiotemporal heterogeneity of factors affecting green total factor productivity in the logistics industry. The results show that the overall level of green total factor productivity in the national logistics industry is gradually improving. The green total factor productivity of the logistics industry in coastal areas is relatively high, while the green total factor productivity of the logistics industry in the middle reaches of the Yellow River, the middle reaches of the Yangtze River, and the southwest region is relatively low; the mechanism of the influencing factors of green total factor productivity in the logistics industry has significant spatiotemporal non-stationary characteristics, and the direction and trend of each factor’s action are different at different spatiotemporal nodes; the progress of urbanization and the density of transportation networks have a positive effect on the green total factor productivity of the logistics industry in most regions. Among them, the density of transportation networks has a negative effect on more complex terrain areas such as the southwest and northwest, while the intensity of energy consumption has a negative impact on the vast majority of regions.
