日本の製造業における参入・退出パターンと生産性
Patterns of Plant Entry and Exit and Productivity in Japanese Manufacturing Industries
要旨Abstract
本論文では，1981-2000年に関する経済産業省『工業統計調査』の事業所レベルのデータを利用し，日本製造業における参入・退出パターンと生産性上昇の関係を分析した．分析により以下の結果を得た．90年の生産性低迷の主因は内部効果の下落であったが，参入効果の下落も生産性低迷にかなり寄与していることが観察された．また，参入率が90年代に大きく下落したことは，参入効果を下落させたのみではなく，90年の生産性低迷の主因である内部効果の下落にも関係していた．我々はまた，参入事業所による市場競争効果が既存事業所の生産性上昇に有意に正の効果を与える一方，参入後の学習効果は既存事業所生産性上昇に負の効果を与える結果を得た．
Using micro-data of the Kogyo Tokei Chosa (Census of Manufactures), which is conducted annually by the Ministry of Economy, Trade and Industry (METI), we examine the relationship between entry and exit patterns, and labor productivity growth in Japanese manufacturing industries. The major findings are the following. We found that the slowdown in Japan's productivity growth was primarily due to the decline of the within effect, but the decline of the entry effect also made a great contribution to the slowdown of labor productivity growth. We also found that the drop of entry rates in 1990s made a contribution to not only the decline of entry effect but also the decline of within effect. Furthermore, we found that the competitive pressures by the entry of new plants have significantly positive effect on productivity growth of incumbents, whereas learning effects show a negative effect on growth of incumbents.
