[Abstract]:After nearly 30 years of development, high-tech industry has played an important role in our national economy. Knowledge R & D and technological progress in high-tech industry are the important driving force of our country's economic growth, and play an important role in guiding our country's economy to change from "investment-driven" to "technology-driven". The new growth theory points out that human capital investment and R & D accumulation are the main influencing factors of technological progress and output growth, especially for high-tech industries. Due to the externality of the production and R & D activities of high and new technology industries, the influence of space factors on the research should be considered in this paper. On the basis of summarizing and analyzing the existing research and introducing relevant theoretical knowledge, this paper establishes a spatial panel model based on the data of China High-Tech Industry Statistical Yearbook and China Statistical Yearbook. This paper analyzes the influencing factors of high-tech industry output in China, and focuses on the effect of knowledge spillover and R & D accumulation on high-tech industry. Firstly, the spatial correlation test of high-tech industry output is carried out to confirm the existence of spatial correlation. Secondly, by introducing R & D accumulation, knowledge spillover and human capital investment, respectively, the spatial lag model, spatial error model and spatial Dobbin model are constructed. To judge and select the optimal model. In this paper, the spatial Doberman model with spatial fixed effect is selected. The results show that: the output of high-tech industries in China has significant spatial correlation and has a positive promotion effect in space; The impact of R & D accumulation on high-tech industrial output is greater than that of labor force and physical capital, and R & D accumulation has significant spatial spillover effect. This means that the output of high-tech industries in a province is affected not only by the accumulation of research and development within the province itself, but also by the accumulation of research and development in neighbouring provinces; on the impact of knowledge spillover on the output of high-tech industries, Due to the externalities of specialization and local competition, there are significant MAR spillovers and Porter spillovers in various regions of China. However, the diversification of high-tech industries has no significant effect on the output of high-tech industries. The possible innovations of this paper are as follows: in the selection of variables, R & D accumulation and knowledge spillover index are introduced to study the impact of R & D accumulation and knowledge spillover on high-tech industry output; in the process of model construction, the spatial correlation of high-tech industry output is considered. The spatial lag model, spatial error model and spatial Doberman model are constructed, and the most appropriate spatial model is selected through the comparison of regression coefficient fitting degree and correlation test.
