黑龙江国有林区林业产业全要素生产率及其影响因素分析

利用DEA法测量了黑龙江省森工40个林业企业的全要素生产率(Total Factor Productiv-ity,TFP),并利用Panel-Data模型找出其影响因素。实证分析结果表明:2003～2009黑龙江国有林区林业企业全要素生产率总体上呈现下降趋势,其原因可归结为林区技术进步缓慢;规模效率和纯技术效率对全要素生产率有正向作用;技术因素和营林投资比重对森工企业的全要素生产率有正向影响,固定资产投资对其存在负向影响,而劳动投入和天保工程(政策因素)对其影响不显著。为此,提出鼓励林业企业技术创新、优化林业投资结构、加强林业投资体制改革、加快森林生态服务的市场化进程和深化林业管理体制改革等建议。

The Analysis of the Total Factor Productivity and its Influencing Factors of Forest Industry in State-Owed Region in Heilongjiang Province

This paper measures the total factor productivity of 40 forestry enterprises which belong to forest industry enterprise in Heilongjiang province,and finds out the influence factors with the Panel-Data model.The analysis results show:the trend of the total factor productivity is overall declining in forestry enterprises in Heilongjiang province from the year 2003 to 2009,which reason can be attributed to the slow technology progress in forest enterprises;scale efficiency and pure technical efficiency has positive effect to total factor productivity;the factors of technology and investment have positive effects to the total factor productivity,investment in fixed assets to its negative effects,and the input of labor and natural forest protection project no significant effects.Based on this,the article put forward to encourage innovation of forestry enterprise technology,optimize investment structure of forestry enterprise,strengthening reform of forestry investment system,accelerate the marketization of forest ecological services and deepen reform of system of management of forestry etc.
