摘要
利用第一手的木材加工企业调查数据,应用规模报酬不变情况下成本效率数据包络分析(DEA)方法,测算各地区木材加工企业成本效率。测算结果表明,平原林区木材加工业成本效率最高,从而验证了平原林区木材加工业具有综合比较优势的经济假说。进而基于Tobit回归模型,分析企业成本效率差异的原因。回归结果显示,建厂时间、所有制性质、产品种类和原材料来源对企业成本效率具有显著的影响。
This paper applied CRS cost efficiency DEA method and new datas to compare wood processing industry efficiency between different regions, and draw a conclusion that the plain forest area scored best, which demonstrated the hypothesis of comprehensively comparative advantage of the plain forest area. Furthermore, the factors that affected enterprises＇ cost efficiency were analyzed by Tobit model, and the regression results showed that time of plant construction, company property, product category, and timber source affected cost efficiency.
