基于中国29个省份的面板数据,采用Malmquist-Luenberger指数,测算各省份全要素碳生产率的增长率,并利用面板门限回归方法,探讨在服务业发展与全要素碳生产率增长的关系中信息化水平的作用。结果表明:1中国多数省份实现了全要素碳生产率增长,多数省份的全要素碳生产率增长主要依靠技术进步而非效率改进。2服务业发展对全要素碳生产率的提升作用受到信息化水平的制约。当地区信息化水平低于一定门限值时,服务业发展对于全要素碳生产率的推动作用较为有限;而当地区信息化水平超过一定门限值时,服务业发展将对当地全要素碳生产率发挥更为积极的推动作用。
Using the Malmquist-Luenberger index to calculate the growth rate of total factor carbon productivity in each province based on the panel data of 29 provinces in China, and using the panel threshold regression method to explore the level of informationization in the relationship between service industry development and total factor carbon productivity growth Role. The results show that: 1 Most provinces in China realized the growth of total factor carbon productivity, and the growth of total factor carbon productivity in most provinces relied mainly on technological progress rather than efficiency improvement. 2 The promotion of service sector’s development on total factor carbon productivity is restricted by the level of informationization. When the level of informatization in the region is lower than a certain threshold, the promotion of service industry will have a limited impetitive effect on total factor carbon productivity. When the level of informatization in the region exceeds a certain threshold, the development of service industry will have an impact on the total factor carbon productivity Play a more positive role in promoting.
