中文摘要：

使用1996～2011年东北国有林区84个森工企业的面板数据，运用超越对数形式的随机前沿生产函数模型，测算了森工企业的技术效率，并计算出各投入要素的产出弹性。然后利用Malinquist生产指数法将全要素生产变化指数分解为技术进步和技术效率变化。结果表明：劳动力和原木的投入对森工企业的产出具有促进作用；1996～2011年东北国有森工企业的平均技术效率值为0．7656，但呈逐年下降的趋势；而全要素生产率的年均增长率为0．51％，其增长主要来自于技术进步，技术效率的下降拖累了全要素生产率的增长，因此，要加强对现有技术的推广和扩散。

英文摘要：

In this paper, the use of state-owned forest zone in 1996 -2011 of Northeast China84 forestry industry panel data, using the stochastic frontier production fianction model beyond the logarithmic form, calculates the tech- nical efficiency of forestry enterprises, and calculate the output elasticity of production factors. Then use the Malin- quist productivity index method of total factor productivity change index is decomposed into technological progress and technical efficiency change. Research results show that： Labor and log input to forestry industry outputcan pro- mote the average technical efficiency; 1996 - 2011 Northeast State-owned forestry enterprise value is 0.7656, but the downward trend; and the annual total factor productivity growth rate is 0.51%, its growth mainly comes from technological progress, the decline of technical efficiency drag the TFP growth, therefore, to strengthen the promo- tion and diffusion of existing technology.
