This paper examines whether the influx of Japanese establishments in colonial Korea during the 1930s suppressed the entry of Korean establishments. We construct new subsector–county-level panel data to exploit variations across counties within subsectors. We find that Korean entry rates were higher in counties with a higher presence of Japanese establishments. However, the spillover effects do vary across subsectors, and we find suggestive evidence of negative impacts of Japanese presence in subsectors with more large-scaled establishments. Taken together, Japanese establishments did seem to raise entry barriers in some subsectors but also functioned as a catalyst for Korean entry in other subsectors.

殖民化下的国内工业化：韩国的证据，1932-1940年

本文研究了1930年代日本人在朝鲜殖民地的大量涌入是否抑制了韩国人的入境。我们构建了新的子部门-县级面板数据，以利用子部门内各县之间的差异。我们发现，在日本机构数量较多的县，韩国的入境率较高。但是，溢出效应在各个子行业之间确实存在差异，并且我们发现日本人存在于规模较大的子行业中的负面影响的暗示性证据。综上所述，日本机构似乎确实在某些子行业中增加了进入壁垒，但也起到了促使韩国人进入其他子行业的催化剂的作用。
