从森工企业的视角出发,就伊春国有林权制度改革,对黑龙江国有林区森工企业的技术效率影响进行了分析。通过Bootstrap-DEA方法计算了黑龙江40个森工企业2003～2010年期间的技术效率值,通过合成控制法依次估计了林权改革对林改企业技术效率的影响。研究发现,林改对铁力森工企业的技术效率提升的影响是巨大的,但是,对于双丰、乌马河和翠峦三个森工企业的技术效率无显著影响。
From the perspective of forest industry and enterprises, this paper analyzes the reform of state-owned forest tenure system in Yichun, and analyzes the technical efficiency of forestry-industrial enterprises in Heilongjiang state-owned forest area. Through the Bootstrap-DEA method, the technical efficiency of 40 forest industry enterprises in Heilongjiang from 2003 to 2010 was calculated. The effects of forest tenure reform on the technical efficiency of forest reform enterprises were estimated by the synthetic control method. The study found that the impact of forest reform on the technical efficiency improvement of the iron-wood forest industrial enterprises was enormous, however, there was no significant effect on the technical efficiency of the three forest industrial enterprises of Shuangfeng, Wumahe and Cuilan.
