长江经济带横跨中西、辐射南北，是中国经济发展的中枢，是缩小区域差距、促进协调发展的关键环节。制造业是长江经济带的优势产业，但企业的粗放发展模式使长江经济带产生了资源枯竭和水体污染等问题。在这种情况下，制造业企业应重视绿色技术创新，在提高生产效率的同时，更注重对环境的保护，找到制造业的最佳发展方向，从而推动长江经济带的高质量发展。本文主要利用2010-2019年长江经济带11个省市制造业面板数据，首先运用动态面板模型分析绿色技术创新对制造业升级的影响效果，并分上、中、下游对长江经济带11省市进行对比分析。得到以下结论：绿色技术创新可以促进长江经济带制造业结构升级、价值链升级和绿色升级。绿色技术创新对不同地区的制造业升级产生不同影响：绿色技术创新对长江经济带中、下游制造业结构升级具有显著的促进作用，对上游地区有抑制作用，但不显著；绿色技术创新对长江经济带上、中、下游制造业价值链升级均有明显的促进作用；绿色技术创新对长江经济带中、下游制造业绿色升级有明显的促进作用，对上游地区有抑制作用。其次，运用空间计量模型分析绿色技术创新对制造业升级的空间溢出效应，得到结论如下：长江经济带绿色技术创新对制造业结构升级和绿色升级都存在显著的空间溢出效应。绿色技术创新对本地和邻近地区的制造业结构升级存在显著的促进作用；绿色技术创新对当地制造业的绿色升级有明显的推动作用，但对周边区域制造业的绿色升级却有一定的抑制作用。在此基础上，提出了相应的政策建议。

The Yangtze River Economic Belt spans the central and western regions of China, and includes the south and the north. It is the center of China's economic development and a key link in narrowing regional gaps and promoting regional coordination.Manufacturing is the dominant industry in the Yangtze River Economic Belt, but the extensive development model of enterprises has caused problems such as resource depletion and water pollution in the Yangtze River Economic Belt.In this case, manufacturing enterprises should pay attention to green technology innovation, improve production efficiency, and pay more attention to the protection of the environment. Find the best development direction of the manufacturing industry, so as to promote the high-quality economic development of the Yangtze River Economic Belt.This paper mainly uses the panel data of the manufacturing industry in 11 provinces in the Yangtze River Economic Belt from 2010 to 2019, and firstly uses the dynamic panel model to analyze the impact of green technology innovation on the upgrading of the manufacturing industry, and analyzes the impact of green technology innovation on the manufacturing industry，and makes a comparative analysis of 11 provinces in the upper, middle and lower reaches of the Yangtze River Economic Belt.The conclusions are as follows: Green technology innovation can promote the structure upgrading, value chain upgrading and green upgrading of manufacturing  in the Yangtze River Economic Belt.Green technology innovation has different impacts on manufacturing upgrading in different regions: Green technology innovation has a significant promoting effect on the structural upgrading of the manufacturing industry in the middle and lower reaches of the Yangtze River Economic Belt, and has a restraining effect on the upstream areas, but it is not significant;Green technology innovation has a significant role in promoting the upgrading of the manufacturing value chain in the upper, middle and lower reaches of the Yangtze River Economic Belt;Green technology innovation has a significant role in promoting the green upgrade of manufacturing in the middle and lower reaches of the Yangtze River Economic Belt, and has an inhibitory effect on the upper reaches of the Yangtze River Economic Belt.Secondly, using the spatial econometric model to analyze the spatial spillover effect of green technology innovation on manufacturing upgrading, the conclusions are as follows: Green technological innovation in the Yangtze River Economic Belt has significant spatial spillover effects on both the structural upgrading and green upgrading of the manufacturing industry.Green technology innovation has a significant role in promoting the structural upgrading of the manufacturing industry in local and neighboring areas; green technology innovation has a significant role in promoting the green upgrading of local manufacturing, but it has a certain restraint on the green upgrading of manufacturing in surrounding areas. effect. On this basis, this paper puts forward some policy recommendations.
