随着企业年龄的增长，企业劳动生产率会呈现怎样的变动趋势？基于2015年中国企业－员工匹配调查数据，对制造业企业劳动生产率的年龄效应进行研究。研究发现：样本总体和内资企业的年龄与劳动生产率之间存在倒U型的非线性关系，外资企业不存在显著的企业年龄效应。经过计算，企业年龄在10年左右时劳动生产率达到最高水平。据此，提出相应的政策建议：鼓励企业加强对劳动力新技术应用的专业性培训，提高人力资本质量，转变发展方式，打破对原始路径的依赖，更加注重质量效益，对冲企业年龄增长带来的劳动生产率负效应。%As the age of the company grows , how would the labor productivity change? Based on the 2015 Chinese Employer-Employee Matching Survey Data , this paper investigates the age effect of labor pro-ductivity in manufacturing companies .According to the results of fixed effect OLS regression , a reverse U-shape relation between the age and labor productivity of firms is found in the full sample and sub sample of en -terprises with domestic investment only , while no significant age effect is found in foreign owned enterprises . After calculation , we find that the labor productivity of firms reaches its highest value at the age of ten .There-fore, this paper reaches the conclusion that firms should be encouraged to offer specialized training on new technology in order to improve the capital quality .Firms should transfer the development mode , break away from dependence on traditional path , and place more emphasis on quality efficiency so as to hedge the negative impact of age increase on labor productivity .
