随着我国环境规制力度的进一步加强，从环境规制视角探讨制造业和生产性服务业融合对碳排放效率的影响亟待深入。为此，基于环境规制视角，利用长江经济带11个省市2000－2020年面板数据，分别运用超效率SBM模型、耦合协调度模型测度区域碳排放效率及传统制造业和生产性服务业融合水平，并采用中介效应、调节效应模型分析环境规制对两业融合与碳排放效率的影响。结果显示：11个省市的平均碳排放效率由2000年的0.811下降至2020年的0.511，整体下降幅度较大，其中上海市的碳排放效率始终处于领先地位；两业融合水平增长速度较快，其中东部地区的融合水平较高，与中西部地区有明显分化；两业融合水平对碳排放效率具有显著的正向影响，环境规制在其中发挥了部分中介作用，同时是有效的调节变量，负向调节两业融合与碳排放效率的关系。基于此，提出长江经济带各地区要因地制宜推动两业融合，打造高端绿色化产业园，并合理制定环境规制政策。

With the further strengthening of environmental regulations in China, it is urgent to explore the impact of the integration of manufacturing and productive service industries on carbon emission efficiency from the perspective of environmental regulations. Therefore, based on the perspective of environmental regulation, using the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2000 to 2020, the super efficiency SBM model and the coupling coordination model are used to measure the regional carbon emission efficiency and the integration level of traditional manufacturing and producer services, and the mesomeric effect and regulatory effect models are used to analyze the impact of environmental regulation on the integration of two industries and carbon emission efficiency. The results show that the average carbon emission efficiency of 11 provinces and cities has decreased from 0.811 in 2000 to 0.511 in 2020, with a significant overall decrease, with Shanghai consistently leading the way in carbon emission efficiency; The growth rate of integration between the two industries is relatively fast, with the integration level in the eastern region being relatively high, which is clearly differentiated from the central and western regions; The level of integration between the two industries has a significant positive impact on carbon emission efficiency, with environmental regulation playing a partial mediating role and being an effective moderating variable. It negatively regulates the relationship between integration between the two industries and carbon emission efficiency. Based on this, it is proposed that various regions of the Yangtze River Economic Belt should promote the integration of the two industries according to local conditions, create high-end green industrial parks, and reasonably formulate environmental regulation policies.
