The Digital Economy,Environmental Regulation and Haze Reduction Effect:An Empirical Study Based on National Big Data Comprehensive Pilot Zone
The digital economy is a new driving force for green and low-carbon development in the new era.Based on the quasi-natural experiment of the national big data comprehensive pilot zone,we construct the theoretical analysis framework of environmental regulations to analyze the impact of digital economy on haze reduction effect.Based on the panel data of 282 cities from 2006 to 2021,we conduct an empirical study using multi-period DID method,instrumental variable method and spatial econometric model.The study finds that:digital economy can significantly promote the improvement of haze reduction effect.In terms of mechanism,digital economy can enhance the haze reduction effect through formal and informal environmental regulations.The enhancement effect of digital economy on haze reduction is more significant in eastern cities,small cities and old industrial base cities.There is a spatial spillover effect of digital economy on the enhancement of haze reduction effect.Therefore,we should further promote the construction of big data pilot areas,improve the construction of digital infrastructure system,and give full play to the role of digital economy in promoting urban haze reduction and control.
