摘　　要：自然资源是环境保护和经济发展的关键要素,可持续发展是整个人类社会共同的诉求,考虑到生态效率在可持续发展中的重要性,本文扩展了"资源诅咒"的研究范围,克服了传统两阶段效率分析的缺陷,首先通过建立条件松弛测度(SBM)模型对生态效率进行测度,然后利用局部线性的非参数估计方法和非参数显著性检验方法,对资源丰裕度与城市可持续发展之间的关系进行经验分析。基于中国258个地级城市2003—2012年的数据样本进行的实证分析发现:中国城市的可持续发展程度总体上处于较低水平,大部分城市的可持续发展指数处于0.5以下,这意味着中国当前经济发展仍以牺牲资源和环境为代价;自然资源丰裕度与生态效率之间存在一个非线性的关系,适度的自然资源丰裕度(8%—15%)能够促进城市的可持续发展,而过低或者过高的资源丰裕度都会对城市的可持续发展造成负作用。Natural resource abundance is a key factor for both environment and development and sustainable development is the common pursuit of the whole human society.Considering the importance of ecological efficiency in sustainable development,this paper expands the research scope of″resource curse″and overcomes the defects of traditional two-stage efficiency analysis.We explore the effect of resource abundance on sustainability performance in China′s cities by developing a conditional slack-based measure(SBM)model to measure sustainability performance considering the influence of exogenous variables.Then a local linear regression and a nonparametric significance test are employed to investigate the role of resource abundance in sustainability performance.This approach is then applied to a unique data set of 258 cities in China during 2003-2012.We have several findings.First,China′s overall sustainability performance was at a low level.For most cities,sustainability scores were below 0.5,indicating that China′s economic growth is still at the expense of her resources and the environment.Second,a nonlinear relationship between resource abundance and sustainability performance was found.Specifically,a moderate level of resource abundance(about between 8%and 15%)plays a positive role in sustainability performance.Otherwise,resource abundance plays a negative role.
