Abstract:     The Fifth Plenary Session of the 19th CPC Central Committee clearly regarded "high-quality development" as one of the important guiding ideologies of economic and social development during the 14th Five Year Plan period. The plenary session pointed out that we should unswervingly implement the new development concept of innovation, coordination, green, openness and sharing, take promoting high-quality development as the theme, coordinate development and security, and accelerate the construction of a modern economic system. The development mode with the main purpose of expanding scale is bound to bring severe consequences such as resource depletion, environmental pollution and ecological damage. The concept of green development has gradually become the inevitable choice for the transformation of China′s economic development mode. Different from the traditional innovation of scale, green innovation follows the rule of economic development, which is the expansion and upgrading of traditional technological innovation, the integration of breakthrough research and development achievements, and fully embodies the dual objectives of environmental protection and innovation development. The energy industry is not only the front end of many industrial chains, but also the basis for all scientific and technological activities, which plays a pillar role in the development of the real economy. The energy industry has the characteristics of high energy consumption and high emission, and has gradually become a key node in the development process of green innovation. Energy industry agglomeration has gradually become an important organizational form of China′s innovation and development and a key force to promote regional technology spillover. 
    Based on the specialized and diversified agglomeration of energy industry, establishing spatial panel econometric model, this study confirms the spatial effect of energy industry agglomeration in the process of green innovation. This study describes the impact of energy industry agglomeration on green innovation performance accurately, and provides new ideas and action plans for the implementation of reasonable green development strategies. Based on the 2009-2017 panel data of 28 provinces in China, the spatial effect of energy industry agglomeration on green innovation performance is empirically tested on the basis of calculating Moran I index. 
    The main conclusions of this study are as follows: First, there is a significant positive spatial autocorrelation in China′s provincial green innovation performance. Second, energy industry specialized agglomeration has a significant negative spatial spillover effect on green innovation performance, and energy industry diversified agglomeration has a significant positive spatial spillover effect and a significant positive total spatial effect on green innovation performance. Third, the specialized agglomeration of energy industry in the eastern region has a significant positive spatial spillover effect and a significant spatial total effect on green innovation performance; The diversified agglomeration of energy industry in central China has a significant negative spatial spillover effect and a significant negative total spatial effect on the performance of green innovation; The specialized agglomeration of energy industry in the western region has a significant positive total spatial effect on green innovation performance, and the diversified agglomeration of energy industry has a significant spatial direct effect on green innovation performance. 
     Finally, corresponding countermeasures are put forward according to the research results: first, enhance the linkage of regional green innovation activities, and give full play to the spatial correlation mechanism of green innovation performance among regions. Second, optimize the development model of energy industry clusters and drive the improvement of green innovation performance. Third, improve the environmental protection supervision and incentive mechanism to ensure the overall improvement of green innovation performance.
