数字经济对江西省绿色全要素生产率的影响研究

Research on the Impact of Digital Economy on Green Total Factor Productivity in Jiangxi Province

数字经济赋能绿色发展是中国经济转型的重要目标,探索数字经济对城市绿色生产要素(GTFP)的影响对建成智慧城市和绿色城市具有重要意义。基于江西省11个地级市2013—2022年的面板数据,采用熵权法和SBM-GML模型计算其数字经济发展水平和GTFP,实证探讨数字经济对江西省GTFP的影响机制以及城市绿色创新能力的中介效应,研究结果表明:数字经济的发展可以显著地促进江西省各个城市GTFP的提升,还可以提高江西省各个城市的绿色创新能力进而推动GTFP的提升。因此,应当培育江西省数字经济发展新引擎,推动城市数字化水平和绿色创新能力的提高,助力江西省GTFP的提升。

Empowering green development with the digital economy is an important goal of China's economic transformation,and exploring the impact of the digital economy on urban green production factors(GTFP)is of great significance for building smart and green cities.Based on panel data from 11 prefecture-level cities in Jiangxi Province from 2013 to 2022,the entropy weight method and SBM-GML model are used to calculate their level of digital economy development and GTFP.The impact mechanism of digital economy on GTFP in Jiangxi Province and the mediating effect of urban green innovation capability are empirically explored.The results show that the development of digital economy can significantly promote the improvement of GTFP in various cities in Jiangxi Province,and can also enhance the green innovation capability of various cities in Jiangxi Province,thereby promoting the improvement of GTFP.Therefore,it is necessary to cultivate a new engine for the development of digital economy in Jiangxi Province,promote the improvement of urban digitalization level and green innovation capability,and assist in the enhancement of GTFP in Jiangxi Province.
