摘要
国家级高新技术产业开发区是我国发展高新技术产业、积极参与国际高技术领域竞争的重要平台,研发投入是高新区集聚发展的重要影响因素。通过构建非线性的门限回归模型,探讨研发投入对高新区集聚发展影响的门限效应,并通过分组回归对门限效应的异质性进行深入研究。结果表明,研发资本投入除了受到自身门限的影响对高新区集聚发展产生逐渐减小的抑制作用外,还随着地区经济发展水平的提升对高新区集聚发展呈现出“抑制-促进-抑制”的作用效果;研发人员投入受自身门限影响对高新区集聚发展产生逐渐变大的促进作用,而随着地区经济发展水平的提升,人才规模比人才质量对高新区集聚发展更有利。在对门限效应异质性进行分析时发现,仅在高校科研水平较高地区才具有门限效应,高校科研水平较低地区的研发投入对高新区集聚发展的影响并不显著。因此,国家在制定高新区发展的政策时应当综合考虑高新区集聚发展水平、地方经济发展状况以及地方高校科研水平的差异,给予地方政府一定的政策调整空间,因地制宜地引导高新区的研发活动和集聚发展。
The national high-tech industrial development zone is an important platform for China to develop high-tech industry and actively participate in the international high-tech competition. Research and development (R&D) investment is the important factor influencing the high-tech zone agglomeration development. By constructing a nonlinear threshold regression model, this paper discussed the threshold effect of R&D investment on the agglomeration development of high-tech zones, and conducted in-depth studies on the heterogeneity of threshold effect by grouping regression. The results show that the investment of R&D capital has a decreasing effect on the agglomeration development of high-tech zones in addition to the influence of its own threshold. With the improvement of regional economic development level, the agglomeration development of high-tech zones shows the effect of "inhibition-promotion-inhibition", and the influence of investment in R&D personnel by their own threshold is gradually increasing in promoting the agglomeration development of high-tech zones. With the development of regional economy, the scale of talents is more important than the quality of talents to the development of high-tech zones. In the analysis of the heterogeneity of threshold effect, it is found that threshold effect only occurs in the areas with higher scientific research level, and the impact of R&D investment on the agglomeration of high-tech zones is not obvious in the areas with low scientific research level. Therefore, when formulating policies for the development of high-tech zones, the state should take into account the level of agglomeration development of high-tech zones, local economic development status and the differences in the level of scientific research in local universities, so as to give local governments some room for policy adjustment. According to local conditions, it should guide the R&D activities and agglomeration development of high-tech zones.
