Spillovers across industries and regions in China’s regional economic diversification
研究1990-2015年中国经济多样化过程中，相关产业和邻近区域的溢出效应如何相互作用，发现两者在解释新企业进入和退出时互为替代，并利用高铁提速缓解内生性问题。
Industrial diversification depends on spillovers from related industries and nearby regions, yet their interaction remains largely unclear. We study economic diversification in China during the period 1990–2015 and present supportive evidence on both spillover channels. We add to the literature by showing that these two channels behave as substitutes when explaining new entries and exits, and by using acceleration campaigns of high-speed rail to address some endogeneity concerns with regional spillovers. Our findings confirm the role of relatedness and geographical distance in the diffusion of economic capabilities and support the idea that improvements in transportation can facilitate the diffusion of productive capabilities.
