【摘要】：高技术产业存在专业化集聚、多样化集聚和市场竞争3种集聚模式,高技术产业集聚与创新产出具有相关性。已有关于高技术产业集聚与创新产出关系的研究忽略了时间和空间因素的影响,导致研究的局限性。基于此,以高技术产业为研究对象,探讨高技术产业集聚模式对创新产出的作用机制。从时间和空间视角,立足于产业整体和五大行业,分别引入时间滞后项、空间滞后项和时空滞后交互项,构建动态空间面板模型,分析高技术产业专业化集聚、多样化集聚和市场竞争3种集聚模式与创新产出的时空效应。研究结果表明,高技术产业创新产出呈现显著的空间依赖特征,表现为空间异质性,整体呈现高-高和低-低的空间集聚分布,同时还具有显著的累积循环效应和空间溢出效应。高技术产业多样化集聚短期内会对创新产出产生负向的区域内和区域间溢出效应,从长期看区域内溢出效应消失,区域间溢出效应由负向转为正向。集聚模式对创新产出的时空效应还存在行业差异,以行业为研究对象时,航空航天器制造业创新产出短期内受到市场竞争的负向区域间空间溢出,电子及通信设备制造业创新产出短期不仅受到专业化集聚和市场竞争的正向区域内空间溢出,还受到多样化集聚对区域整体的负向空间溢出,其他行业的创新产出没有受到集聚的显著影响;从长期看产业集聚对创新产出的空间溢出效应并不显著。研究结果丰富了高技术产业集聚与创新产出关系的相关经验研究,为高技术产业集聚模式的选择提供了经验证据,为高技术产业创新产出发展提供了战略方向。
[Abstract]:There are three kinds of agglomeration modes: specialized agglomeration, diversified agglomeration and market competition in high-tech industry, and the agglomeration of high-tech industry is related to innovation output. The research on the relationship between hi-tech industry agglomeration and innovation output neglects the influence of time and space, which leads to the limitation of the research. Based on this, the mechanism of high-tech industry agglomeration on innovation output is discussed. From the angle of view of time and space, based on the whole industry and five industries, this paper introduces the time lag term, the spatial lag term and the space-time lag interaction item, constructs the dynamic spatial panel model, and analyzes the specialized agglomeration of high-tech industry. Diversification agglomeration and market competition: three kinds of agglomeration modes and the spatiotemporal effect of innovative output. The results show that the innovation output of high-tech industry shows significant spatial dependence, which is characterized by spatial heterogeneity, high and low spatial agglomeration. At the same time, there are significant cumulative cyclic effects and spatial spillover effects. The diversification agglomeration of high-tech industries will produce negative intraregional and inter-regional spillover effects on innovation output in the short term. In the long run, the intra-regional spillover effects will disappear, and the inter-regional spillover effects will change from negative to positive. There are industry differences in the spatiotemporal effects of agglomeration mode on innovation output. When the industry is taken as the research object, the innovation output of aerospace manufacturing industry is subject to negative inter-regional spatial spillover of market competition in the short term. The innovation output of electronic and communication equipment manufacturing industry is not only subject to positive intraregional spatial spillover due to specialization agglomeration and market competition, but also to negative spatial spillover of diversification agglomeration to the whole region. The innovation output of other industries is not significantly affected by agglomeration; the spatial spillover effect of industrial agglomeration on innovation output is not significant in the long run. The results enrich the empirical research on the relationship between high-tech industry agglomeration and innovation output, provide empirical evidence for the choice of high-tech industry cluster model, and provide strategic direction for the development of high-tech industry innovation output.
