从单一的经济增长视角拓展到多维的生态效率视角来考察资源诅咒是否成立,对于区域发展方式转变具有重要意义。利用新的数据包络模型测算2001年-2011年中国省域生态效率,比较了资源开发型和资源利用型区域的生态效率差异,测度了规模效应的贡献,提出并利用结构控制法构造对照样本,考察了资源开发型区域中两类部门的效率差异及其贡献。研究发现:基于经济增长维度的比较表明资源诅咒现象不明显;资源利用型区域的生态效率平均为资源开发型区域的1.6倍以上,表明基于经济、资源和环境等多维视角时资源诅咒现象显著存在。对资源开发型区域的进一步研究显示,其生态效率有60%以上来源于规模效应,且其资源利用部门的效率严重低于资源开发部门的水平,对总体生态效率的贡献不到40%。资源诅咒现象和生态效率偏低的主要原因不是资源开发,而是资源丰裕环境下的资源浪费行为。解决问题的关键不在于改变资源开发策略,而在于提高资源利用效率。
It is of great significance to the transition of regional development that whether the resource curse is supported from a multidimensional perspective,i.e.,economy,resource and environment,instead of only considering the economic growth.An improved DEA model is used to measure provincial eco-efficiency in China from 2001 to 2011,and the difference between resource-dependent regions and resource-utilizing ones is compared.The empirical results show that resource curse phenomenon is not significant from the economic dimension,yet is significant from the multidimensional perspective,for the eco-efficiency of resource-utilizing is about 1.6times of that of resource-dependent regions.Over 60% of eco-efficiency in the resource-dependent regions comes from scale effects.And the efficiency of resource-utilizing sectors in those regions is severely lower than that of resource exploration sectors,which contributes less than 40%to those regions' eco-efficiency.The key reason for low eco-efficiency may not be resource exploration but resource wastes in an environment with abundant resource.So improving resource utilization is one of the keys to enhance eco-efficiency.
