深圳高新电子信息企业空间格局演化及其影响因素

基于深圳市2007—2017年电子信息类高新技术企业名录数据，通过全局墨兰指数、核密度分析与热点分析研究深圳市高新电子信息企业的空间集聚与演化特征，运用空间回归模型分析其影响因素及变化。结果表明：在研究时段内，高新电子信息企业全局集聚强度进一步升高，其分布经历了“集聚-分散-集聚”的变化过程；企业空间集聚由“双核共振”转变为“三足鼎立”格局，并形成“高新园区型”、“老工业区型”和“龙头企业型”三种集聚模式；园区政策、产业集聚一直是深圳电子信息技企业分布的关键影响因子，交通和区位等基础因素影响相对偏弱；影响因素的变化显示出产业集聚、对外交通因子的影响显著提升，知识技术因子的影响开始显现。

The spatial evolution of Shenzhen high-tech electronic information technology agglomeration pattern and locational determinants

Based on 2007- 2017 high-tech enterprises datasets of electronic information industry of Shenzhen, this essay used Moran's I index, Kernel density estimation, and Hot spot analysis to recognize the patterns and changes of geographical agglomeration of high-tech electronic information technology(HEIT) enterprises in Shenzhen. By employing a spatial regression model, we analyzed its locational choice in two stages of 2007 and 2017. Results show that: In the research period, Shenzhen HEIT enterprises present a higher level of global agglomeration, and its distribution experienced a change process of "agglomeration, dispersion, and re-agglomeration"; The spatial agglomeration has changed from "dual-core" to "triple-core" pattern, resulting in three kinds of clusters, including high-tech park oriented, historical industry area oriented and leading-enterprise oriented; Policy influence and industrial agglomeration effect play critical roles in making the locational choice for Shenzhen HEIT enterprises, while basic factors such as the accessibility of transportation has a moderate impact. In the latter stage, with the internalization of early input factors by government, the influence on the locational decision of IET enterprises is significantly increased, and its dependence of technology level and external traffic accessibility begins to manifest.
