产业融合发展是产业经济发展的新特征和新趋势，模糊了产业间的边界，推进了产业的快速发展。国家的相关政策、信息技术和数字经济等的快速发展，更是助推了产业间更大范围和更深领域的深度融合发展，进而助力我国经济的高质量发展、促进我国的全要素生产率，而经济不断发展引来的环境问题同样是我们需要关注的重点问题，那么，绿色高质量发展便成了重中之重。现代服务业和先进制造业是广泛使用现代化技术、现代化体系、现代化管理和现代化模式的制造和服务业，具有很强的关联性，专业化的现代服务为制造业实现转型升级提供了重要支持，而先进制造业的高层次需求是现代服务业实现转型升级所需的可靠载体。如何高效利用现代服务业与先进制造业间的融合发展，进而为我国经济向绿色高质量转型升级，助推绿色全要素生产率是本文重点研究的问题。

本文首先基于2012到2020年的现代服务业与先进制造业的数据，通过耦合协同模型测算了二者的产业融合度，分析了区域差异性和空间效应；其次，采用SBM-GML测算了绿色全要素生产率和其分解项。最后建立动态面板数据模型，采用GMM估计方法，实证检验了现代服务业与先进制造业融合发展对绿色全要素生产率的影响。结果表明：(1)我国现代服务业与先进制造业融合发展处于不断提升的趋势，分区域南部优于北部，且差距不断拉大，并且存在显著的空间效应。(2)我国绿色全要素生产率整体上呈现上升趋势，分解项技术进步整体上也呈现上升态势，而技术效率存在一定的下降态势。(3)产业融合对绿色全要素生产率有正向的促进作用，分南北区域，对南部有显著的正向促进作用，对北部有显著的负向抑制作用，说明南北区域间的发展差距逐渐拉大。在研究产业融合对绿色全要素生产率的影响过程中，不仅对现代服务业与先进制造业的融合情况进行了整体、分区域和空间效应探究，而且对其绿色全要素生产率的分解项进行了探究，对于产业融合赋能绿色全要素生产率具有现实指导意义。

根据结论本文提出了相对应的政策建议：积极推进现代服务业与先进制造业融合发展的驱动力；促进各区域技术的有效转化，鼓励推出区域间差异化政策。

The development of industrial integration is a new feature and trend of industrial economic development, which blurs the boundary between industries and promotes the rapid development of industries. The relevant national policies, the rapid development of information technology and digital economy, etc., have boosted the development of deeper integration between industries to a greater extent and in a deeper field, thus helping our economy to develop with high quality and promoting our total factor productivity, while the environmental problems caused by the continuous development of the economy are also the key issues that we need to pay attention to. Modern service industry and advanced manufacturing industry are manufacturing and service industries that widely use modern technology, modern system, modern management and modern mode, which have strong correlation. Specialized modern services provide important support for manufacturing industry to realize transformation and upgrading, while the high-level demand of advanced manufacturing industry is a reliable carrier for modern service industry to realize transformation and upgrading. How to efficiently utilize the integration development between modern service industry and advanced manufacturing industry, and then contribute to green total factor productivity for China's economic transformation and upgrading to green and high quality is the key research issue in this paper.

Based on the data of modern service industry and advanced manufacturing industry from 2012 to 2020, this paper first measures the degree of industrial integration through the coupling synergy model, and analyzes regional differences and spatial effects. Secondly, SBM-GML is used to measure green total factor productivity and its decomposition terms. Finally, a dynamic panel data model is established and the GMM estimation method is used to empirically test the impact of the integrated development of modern service industry and advanced manufacturing industry on green total factor productivity. The results show that: (1) The integration and development of modern service industry and advanced manufacturing industry in China is in a rising trend, the southern part of the subregion is better than the north, and the gap is widening, and there is a significant spatial effect. (2) China's green total factor productivity shows an upward trend as a whole, and the technological progress of decomposition items also shows an upward trend as a whole, while there is a certain decline in technical efficiency. (3) Industrial integration has a active effect on green total factor productivity, divided into north and south regions, has a significant positive promotion effect on the south, and has a significant negative inhibitory effect on the north, indicating that the development gap between the north and south regions is gradually widening. In the process of studying the impact of industrial integration on green total factor productivity, not only the integration of modern service industry and advanced manufacturing industry is explored as a whole, sub-region and spatial effect, but also the decomposition of green total factor productivity is explored, which has practical guiding significance for industrial integration to empower green total factor productivity, and according to the above conclusions.

This paper puts forward corresponding policy suggestions: The driving force for actively promoting the integration and development of modern service industry and advanced manufacturing industry; Promote the effective transfer of technology in various regions and encourage the introduction of differentiated policies between regions.
