信息扩散、产业集聚与区域技术创新绩效——基于2005—2018年区域面板数据的动态分析

为了探索信息扩散、产业集聚与技术创新绩效间的动态影响关系，寻找影响地区经济发展及技术创新驱动的主要因素，使用2005—2018年我国区域面板数据，采用VAR模型、面板数据模型及状态空间模型，对信息扩散、产业集聚与技术创新绩效关系进行分析。研究发现：①产业集聚对技术创新绩效的边际影响力呈倒U形曲线，而信息扩散对技术创新绩效的边际影响力呈递增趋势，信息扩散对产业集聚的边际影响力呈线性增长态势，而技术创新绩效对产业集聚的边际影响力呈倒U形曲线；②不同地区信息扩散与产业集聚对技术创新绩效的影响效应依次为东部地区＞中部地区＞西部地区，且东部和中部地区的信息扩散对技术创新绩效的影响大于产业集聚的影响，西部地区的产业集聚对技术创新绩效的影响大于信息扩散的影响；③不同地区信息扩散与技术创新绩效对产业集聚的影响效应依次为东部地区＞中部地区＞西部地区，且东部地区的技术创新绩效对产业集聚的影响大于信息扩散的影响，中部和西部地区信息扩散对产业集聚的影响大于技术创新绩效的影响。

Informatization Diffusion,Industrial Cluster and Technological Innovation Performance based on Regional Panel Data from 2005 to 2018

In recent years, China has been stepping up efforts to promote the construction of the national economic circle and the technology innovation-driven strategy to create emerging industrial economic zones and technological innovation platforms of our country.Industrial cluster is a phenomenon that competitive industries, professional suppliers, service providers, manufacturers and related industrial organizations gather in certain fields or regions.Industry clustering puts forward new requirements on the level of technological innovation, thereby driving the continuous upgrading of regional or national technological innovation.Meanwhile, in recent years, informatization construction of our country has been rapidly carried forward.The rapid information diffusion brought by informatization construction has promoted the sharing and exchange of international and domestic knowledge, and has accelerated the flow of information, the diffusion of knowledge, and the interactive integration of knowledge in multiple fields, and has also promoted national or regional technological innovation so that informatization construction, industrial cluster and technological innovation have become important strategies for national development.Therefore, exploring the relationship between information diffusion, industrial cluster and technological innovation performance is greatly significant to the development of national technology and economy.In order to seek for the main influencing factors of economic development and technological innovation in different regions, the paper explores the relationship between informatization level, industrial cluster, and technological innovation performance.The paper uses China′s regional panel data from 2005 to 2018, and uses VAR model, panel data model, and state space model to analyze the relationship between informationization level, industrial cluster, and technological innovation performance.The paper gathered data come from the China Statistical Yearbook, Qingbo Database, China Science and Technology Statistical Yearbook, China Internet Development Report, Wind database, Guotaian CSMAR database, and selected ten medium-sized industries from 2005 to 2018 and relevant indicators for the research object.The research finds that (1) The change of the marginal influence of industrial agglomeration on technological innovation performance is an inverted U-shaped parabola, and the marginal influence of informatization level on technological innovation performance is increasing.The marginal influence of informatization level on industrial agglomeration shows a linear growth trend, while the change in the marginal influence of technological innovation performance on industrial agglomeration is an inverted U-shaped parabola.(2) The order of the effect of informationization level and industrial agglomeration on technological innovation performance is Eastern, Central, and Western regions, and the impact of informationization levels on technological innovation performance in eastern and central regions is greater than the impact of industrial agglomeration.The impact of industrial agglomeration in the western region on the performance of technological innovation is greater than the impact of informatization level.(3) The order of the effects of informatization level and technological innovation performance on industrial agglomeration is eastern, central, and western regions, and the impact of technological innovation performance on industrial agglomeration in the eastern region is greater than the impact of informationization level.The impact of informatization in the western region on industrial agglomeration is greater than the impact of technological innovation performance.This paper put information diffusion, industrial cluster and technological innovation in the same theoretical framework as a systemic structure for model construction, analyzed the impulse response and marginal influence of endogenous variables, and analyzed the difference of the influence of various variables in different regions.The research findings had great significance for technological innovation upgrading and industrial development.In theory, it can help to construct a long-term balanced and effective theoretical model of technological innovation and industrial development which agrees with the reality of our country.In practice, the improvement of information diffusion can be used to promote industrial upgrading and drive technological innovation.Technological innovation and industrial cluster can also promote the improvement of regional or national information diffusion.Based on this, we can find the main influencing factors of economic development and technological innovation in specific regions, so as to formulate driving strategies and specific measures that conform to the policy of specific regional economic development and technological innovation.
