How can National Comprehensive Big Data Pilot Zone promote green transformation of cities:Based on the dual perspective of the growth rate of carbon emissions and carbon productivity
The comprehensive implementation of the national big data strategy is an important initiative to promote high-quality development. This paper analyzes the data of 276 prefecture-level cities in China from 2011 to 2021,and adopts the asymptotic difference-in-difference method to study the impact of the National Big Data Comprehensive Pilot Zone ( hereinafter referred to as the"Big Data Pilot Zone") policy on the green transformation of cities based on the dual perspectives of the growth rate of carbon emissions and the growth rate of carbon productivity. The results show that the policy can effectively drive the green transformation of cities and passes several robustness tests. In addition,there are significant differences in construction goals and policy effects across pilot zones,and the overall policy effects are highly heterogeneous in terms of the level of infrastructure and ecological resilience of cities. The intrinsic mechanism test finds that the policy achieves the goal of urban green transformation by promoting green technological innovation,facilitating the widespread use of robots,and optimizing the industry in all aspects. Further analysis reveals that the government's digital focus and the city's innovation level have a good moderating effect on the policy's effectiveness,while the policy also has a significant effect on reducing the increase in the city 's electricity consumption,enhancing intellectual property protection,and improving environmental quality. This paper provides important empirical evidence to validate the impact of the Big Data Pilot Zone policy on the city's green transformation as well as to further promote the Big Data strategy and the high-quality development of the digital economy.
