补贴与全要素生产率——来自中国装备制造企业的实证研究

Subsidy and total factor productivity: An empirical study from the Chinese equipment manufacturing enterprises

使用中国工业企业数据库1999-2007年装备制造业企业数据,采用PSM方法、Malmquist指数分解法和动态OP分解法对补贴与全要素生产率间关系及补贴企业全要素生产率增长源泉进行分析。结果表明:补贴企业的全要素生产率小于非补贴企业;补贴企业的生产率增长主要源于技术进步和自身成长,规模效率(或资源配置效率)和纯技术效率贡献度较小。

Based on panel data of Chinese equipment manufacturing enterprises from1999to2007,and using the method of propensity score matching(PSM),Malmquist index productivity decomposition and dynamic Olley-Pakes productivity decomposition,the present essay analyzes the relationship between subsidy and total factor productivity as well as the growth source of total factor productivity of subsidy enterprises.The results show that the total factor productivity of subsidy enterprises is less than non-subsidy enterprises,that the productivity improvements of subsidy enterprises mainly depend on technological progress and self-growth,and that scale efficiency(or resource allocation efficiency)and pure technical efficiency contribute less.
