行业内正向和负向外溢效应影响城市工业布局中技术扩散的有效性。目前关于外溢效应的实证研究没有隔离出同时存在的正向和负向外溢效应,并且缺乏针对城市聚集的分析。鉴于此,使用中国2000-2007年制造业市际面板数据进行分析,结果表明,总体而言目前正向的技术扩散和负向的“挤占”效应同时存在,而城市范围内的产业聚集并没有促进正向外溢效应的发挥。为此,政府应适时结合人力资本、基础设施、竞争环境等进行政策调整。
Positive and negative spillover effects in the industry affect the effectiveness of technology diffusion in urban industrial layout. At present, the empirical research on spillover effects does not isolate the positive and negative spillover effects that exist at the same time, and lacks the analysis of urban agglomeration. In view of this, the analysis using China’s manufacturing panel data from 2000 to 2007 shows that, overall, the current positive technology diffusion and the negative “crowding-in” effect co-exist, while the urban-based industries gather Did not promote the positive spillover effect. To this end, the government should make timely policy adjustments in combination with human capital, infrastructure and competitive environment.
