摘要：
从空间溢出视角理解高技术产业集聚，对于城市获取经济和技术竞争优势至关重要。随着快速城市化以及快速交通网络的发展，城市之间的社会经济互动日益增强，传统的空间度量指标已不足以描述实际的城市间联系。城市间的高技能劳动力流动对高技术产业集聚具有强烈影响，但受到的关注较少。通过利用独特的大规模数据集以及来自复杂网络和数据挖掘的工具，我们构建了一个城市间高技能劳动力流动网络，并将其纳入空间计量模型。我们的回归结果表明，在长江三角洲城市群地区的高技术产业发展中存在空间溢出效应。此外，与仅具有较强地理联系的城市相比，高技能劳动力流动量较高的城市之间空间溢出效应更强。另外，我们考察了溢出效应的渠道，发现地方政府科技支出不足可能阻碍高技术产业集聚，地方教育供给不足同样如此。某一城市不断增加的外商直接投资可能会促进其他城市的高技术产业集聚，原因在于面向传统产业的政策惯性。
英文摘要：
Understanding the high-tech industrial agglomeration from a spatial-spillover perspective is essential for cities to gain economic and technological competitive advantages. Along with rapid urbanization and the development of fast transportation networks, socioeconomic interactions between cities have been ever-increasing, traditional spatial metrics are not enough to describe actual inter-city connections. High-skilled labor flow between cities strongly influences the high-tech industrial agglomeration, yet receives less attention. By exploiting unique large-scale datasets and tools from complex network and data mining, we construct an inter-city high-skilled labor flow network, which was integrated into spatial econometric models. Our regression results indicate that spatial-spillover effects exist in the development of high-tech industries in the Yangtze River Delta Urban Agglomeration region. Moreover, the spatial-spillover effects are stronger among cities with a higher volume of high-skilled labor flows than among cities with just stronger geographic connections. Additionally, we investigate the channels for the spillover effects and discover that inadequate local government expenses on science and technology likely hamper the high-tech industrial agglomeration, so does the inadequate local educational provision. The increasing foreign direct investments in one city likely encourages the high-tech industrial agglomeration in other cities because of the policy inertia toward traditional industries.
