Outline of Final Research Achievements

This study examines the technical inefficiency of small and medium Japanese firms in both manufacturing sector and non-manufacturing sector by using panel data from the Basic Survey on Small and Medium Enterprises (2009-2018). We estimate the stochastic frontier production function with four production factors (regular workers,non-regular workers, capital stock and materials) and calculate the technical inefficiency of individual firms by applying a true random effects model that can distinguish technical inefficiency from firm heterogeneity.
We find that inefficient firms are smaller, rely more on non-regular workers, exhibit poorer firm performance, measured by profitability and marginal q, have a higher debt-asset ratio, pay a lower interest rate (ever-greening by financial institutions) and are inactive in capital investment and R&D investment. We also find that inactive capital investment and a high debt-asset ratio are mainly responsible for causing technical inefficiency.

Academic Significance and Societal Importance of the Research Achievements

日本経済が成長経路に乗るためには、技術革新を活発化して潜在成長力を高めることが不可欠である。しかし、わが国の中小企業はイノベーションに乏しく、国際的に見ても生産性が低いと指摘されてきた。この研究では、中小企業の低生産性の原因を技術的非効率性という視点から実証的に解明を行った。
企業のミクロデータを用いて、技術的非効率性の源泉とそのインパクトを体系的に把握することに成功した。技術的非効率性は、雇用形態(非正規雇用の割合)、設備投資や研究開発投資の実施状況に大きく左右されることがわかった。また、実証結果に基づいて技術的非効率性を克服するために有効な政策提言も行った。
