考虑非期望产出的资源型城市低碳转型阶段性及TFP评价

Multidimensional Evaluation of Low Carbon Transition Efficiency of Resource-based Cities Based on Unexpected Output

摘要:

资源型城市在中国国民经济发展过程中扮演着重要角色,为国家经济建设提供了大量自然资源。然而随着自然资源的过度开采,资源型城市面临着资源耗尽和环境污染等问题,资源型城市要实现可持续发展,必须进行低碳转型升级。基于此本文首先阐释了资源型城市低碳转型的影响制约因素,构建了低碳转型评价的指标体系,并对转型等级进行了划分,在此基础上确定了考虑非期望产出的SBM评价模型,以17个典型资源型城市为例,通过ML指数及TFP分解值在不同年度的差异化变动进行了实证评价,以检验评价系统的科学性和可行性。

Abstract:

Resource-based cities play an important role in the development of China"s national economy, which have provided a great deal of natural resources for the national economic construction. However, with the over-exploitation of natural resources, resource-based cities are facing serious problems such as resource depletion and environmental pollution. In order to achieve sustainable development, resource-based cities must carry out low-carbon transformation and upgrading. Based on this, Firstly, they are discussed on the influencing factors of low-carbon transformation of resource-based cities. The evaluation index system of its low-carbon transformation efficiency is constructed, and the transformation level is divided. On this basis, SBM evaluation model considering unexpected output is established, and Taking 17 resource-based cities as an example, this paper makes an empirical evaluation from the perspective of average value and difference in different years to test the Scientific nature and feasibility of the evaluation system.
