物流业高质量发展对制造业绿色全要素生产率的影响研究

Study on the Impact of Quality Development of Logistics Industry on Green Total Factor Productivity of Manufacturing Industry

文章选取了全国30个省和直辖市的面板数据,构建了物流业高质量发展水平的指标体系。同时,运用了无超效率SBM-GLM模型对制造业绿色全要素生产率进行测度,并且运用双向固定效应模型和门槛效应模型进行分析。得出了以下结论:(1)物流业高质量发展对制造业绿色全要素生产率的系数显著为正,说明物流业高质量发展水平对制造业绿色全要素生产率有着显著的正向促进作用。(2)物流业高质量发展水平对制造业绿色全要素生产率的影响存在着非线性的关系。这说明物流业高质量发展水平只有达到一定的门槛水平,才能真正的对制造业绿色全要素生产率发挥提升作用。

In this paper,panel data from 30 provinces and municipalities directly under the central government are selected for analysis,and an indicator system for the high quality development level of the logistics industry is constructed.At the same time,a super-efficiency-free SBM-GLM model was used to measure the green total factor productivity of the manufacturing industry,and a two-way fixed-effects model and a threshold-effects model were used to empirically analyse the impact of the high-quality development level of the logistics industry on the green total factor productivity of the manufacturing industry.The following conclusions were drawn:(1)The coefficient of the high quality development of the logistics industry on the green total factor productivity of the manufacturing industry is significantly positive,indicating that the high quality development level of the logistics industry has a significant positive contribution to the green total factor productivity of the manufacturing industry.(2)There is a non-linear relationship between the impact of the level of quality development of the logistics industry on green total factor productivity in the manufacturing industry.This indicates that only when the level of quality development of the logistics industry reaches a certain threshold level can it truly play a role in enhancing the green total factor productivity of the manufacturing industry.
