Outline of Final Research Achievements

An analysis was conducted using firm-level data and GIS data of China and Indonesia to investigate the role of urban and industrial agglomerations in industrial development. The following observations were obtained: (1) Industrial agglomeration had the effect of increasing the productivity of small businesses. (2) China's urban agglomeration "tolerated” low-productivity firms. (3) Whether low-productivity firms were selected more severely in urban and industrial agglomeration areas was not clear, but younger firms tended to be selected more easily. (4) Firms were younger and competition was more intense in China than in Indonesia.

Academic Significance and Societal Importance of the Research Achievements

企業間の異質性を考慮した研究が進み，伝統的にいわれてきた集積の経済効果について過大評価の可能性が指摘されるなど，とくに新興・途上国において都市・産業集積が期待される産業・企業育成の役割について，実証的根拠の再確認が必要になっていた。そうした状況下で中国とインドネシアについて分析を行い，有意義なエビデンスを得ることができた。
