Abstract The regional innovation system is the foundation and an important part of the national innovation system, and its formation and development play a significant role in promoting national technical innovation. The improvement of regional innovation performance has become a key issue to develop the regional innovation system. However, there are great distinctions in innovation performance among different regions in China, which are also presented in the two stages of regional innovation activities. Industrial agglomeration is one of the important reasons for this phenomenon. While because of the impact of economies of scale, similar enterprises tend to gather in the same regions, which keeps the regional technical endowment at a stable level and deepens the distinctions in the intensity of technical endowment among regions. Technical endowment determines the types of technologies suitable for regions and affects the regional growth, upgradation and transformation of industries by influencing knowledge spillover, talent structure and production efficiency. Therefore, the technical endowment also bring different impacts of industrial agglomeration on regional innovation activities in the two stages. The existing studies only analyze the impact of industrial agglomeration on regional innovation performance from the perspective of different industrial structures, without considering the intensity of regional technical endowment. They have also ignored the stage characteristics of regional innovation activities, which has become one of the obstacles restricting the overall development of industrial agglomeration and regional innovation growth. Therefore,from the perspective of value chain, this study divides the process of regional innovation into two stages: knowledge creation and achievement transformation. Introducing the intensity of regional technical endowment, this study discusses the distinction of the impact of industrial agglomeration on regional innovation performance in two stages when the intensity of regional technical endowment is taken as the threshold variable.#br#This paper selects 30 provincial administrative regions in China from 2009 to 2019 as research samples, and the original data of these regions is from various statistical yearbooks and platforms in China.A threshold regression model is constructed to explore the impact of industrial agglomeration on regional innovation performance with the different regional intensity of technical endowment. To obtain a stable conclusion, two tests are conducted to verify the robustness of the conclusion.#br#The results show that the influence of industrial agglomeration on the two-stage performance of regional innovation has significant nonlinear threshold characteristics. In the stage of knowledge creation, as the intensity of regional technical endowment increases, the promoting effect of industrial agglomeration on the performance of regional innovation rises gradually. In the stage of achievement transformation, when the intensity of regional technical endowment increases, the association between industrial agglomeration and regional innovation performance first decreases and then rises. Combining the results of the two stages,the study confirms that the industrial agglomeration of most regions in China can promote regional innovation performance in the two stages. Technical endowment tends to concentrate on the regions with the strongest economic foundation within a certain geographical range at first, and then these regions gradually drive the growth of the intensity of technical endowment in other neighboring regions.#br#This study extends the boundary of the industry cluster theory and the new economic geography theory, andenriches the research on the relationship between industrial agglomeration and regional innovation performance in the field of technical endowment, as well as the research content of innovation geography to a great extent. Moreover it provides a theoretical basis for the government of regions with different intensities of technical endowment to promote regional innovation development by industry introduction, thuspromoting regional innovation and coordinated development.#br#
