Research on the Impact of Digital Economy on Green Total Factor Productivity of Manufacturing Industry:A Quasi Natural Experiment Based on National Big Data Comprehensive Experimental Zone
As a high energy consuming and highly polluting industry,manufacturing plays a significant role in the secondary industry.Exploring the green transformation and development of manufacturing is of great practical significance.Based on panel data from 30 provinces in China from 2005 to 2020,the SBM-GML model was first used to measure the green total factor productivity of the manufacturing in-dustry.Subsequently,the establishment of a national level big data comprehensive experimental zone was regarded as a quasi natural experiment,and the impact of the digital economy on the green total factor productivity of the manufacturing industry was empirically tested in stages using a multi-period DID method.The results show that the construction of national level big data comprehensive experimen-tal zones can significantly improve the green total factor productivity of the manufacturing industry,and has robustness.Heterogeneity testing shows that the construction of the big data comprehensive experi-mental zone can significantly improve the green total factor productivity of the manufacturing industry in the eastern and central regions,and the effect on the central region is more significant.Mechanism tes-ting has found that the construction of big data comprehensive pilot zones can improve the green total factor productivity of the manufacturing industry by suppressing labor mismatch,increasing research and development intensity,and promoting industrial structure upgrading.Further analysis shows that with the development of the digital economy and the improvement of green innovation capabilities,the impact of the digital economy on the green total factor productivity of the manufacturing industry is non-linear,and both exhibit a U-shaped relationship of first inhibition and then promotion.
