高速铁路建设对知识密集型服务业发展的影响:一个实证

the Impact of High-speed Rail Construction on the Development of Knowledge-intensive Service Industry:An Empirical Study

知识和创新溢出存在空间壁垒,高速铁路能打破区域空间阻隔,缩小时空距离,促进以知识和创新为显著特征的知识密集型产业发展。构建2006-2015年省级面板数据,使用固定效应模型,从区域层面和细分产业层面研究高速铁路建设对我国知识密集型服务业发展的影响。结果发现,高速铁路建设与我国知识密集型服务业从业人员数量增加呈显著正相关关系;对东部地区知识密集型服务业发展影响不够显著,但对中西部地区知识密集型服务业固定资产投资起显著促进作用。这表明,高速铁路修建改善了区域投资环境,打破了区域阻隔,有助于增进知识溢出效应、加速要素流动,对中西部地区知识密集型服务业发展和产业升级具有重要意义,进一步证实在中西部地区建设高速路具有正确性和必要性。

The spillovers of knowledge and innovation exist space barrier, and high-speed rail further breaks the gap of regional space, reduces the distance of time and space, and promotes the development of knowledge-intensive industry which is characterized by knowledge and innovation. Construct the provincial panel data of 2006 to 2015 and use fixed effect to study the impact of high-speed rail construction on the development of the knowledge-intensive service industry from the regional level and the industry level in China. Find that the high speed rail construction has a positive impact on the in- crease of the number of practitioners of the knowledge-intensive service industry in China and plays a promoting role in the fixed assets investment of knowledge-intensive service industry in Midwest. Fully illustrated, the high-speed rail construction can improve the regional investment environment, break the regional barriers, promote knowledge spillovers, accelerate the flow of factors, and has great significance to the development of knowledge-intensive service industry and industrial upgrading in the central and western regions. That further confirmed the correctness and the necessity of the construction of high-speed rail in Midwest.
