二氧化硫减排治理对重污染企业综合指数影响分析

Analysis of the impact of sulfur dioxide emission reduction and control on the comprehensive index of heavily polluting enterprises

针对二氧化硫污染减排治理技术对企业生产效益的影响,利用2013年至2022年期间所选企业的面板数据,尝试性地对影响状况实施深入研究和剖析。构建企业的生产函数,实施二氧化硫污染减排治理技术对企业生产影响因素的分类,完善企业生产函数。结果表明,技术投资成本、运行与维护成本、技术创新在10%的水平上显著;生产效率、资源利用、企业成长率环保合规性、生产成本在5%的水平上显著;产品质量、劳动力投入在1%的水平上显著。相比混合OLS回归结果,技术投资成本等几项的作用系数均有所降低,环保合规性的作用系数则有一定升高。

In view of the impact of sulfur dioxide pollution reduction and control technology on the production efficiency of enterprises,the panel data of selected enterprises from 2013 to 2022 were used to carry out in-depth research and analysis of the impact status.The production function of the enterprise was constructed,the classification of the influencing factors of the production of the enterprise by the sulfur dioxide pollution reduction control technology was implemented,so as to improve the production function of the enterprise.The results showed that the cost of technology investment,operation and maintenance,and technological innovation were significant at the level of 10%,and the production efficiency,resource utilization,enterprise growth rate,environmental compliance,and production cost were significant at the level of 5%.Product quality and labor input were significant at the level of 1%.Compared with the mixed OLS regression results,the coefficients of technology investment cost and other items were reduced,while the coefficients of environmental compliance were increased.
