中国经济的快速发展加剧了环境污染和能源短缺等问题。因此，近年来，建立一个资源节约和环境和谐的社会，典型地再利用来自工业生产的污染和废物，已经引起了政府和公众的关注。数据包络分析（DEA）被广泛应用于度量由同质决策单元构成的两阶段网络结构。然而，以往的工作未能考虑到不良的中间产品的两阶段网络结构，包括生产系统和处置系统。在这项研究中，我们建立了一个加性DEA方法来评估所提出的新的两阶段网络结构的效率，并提出了一个更好的效率分解到单个系统。最后，我们的方法被应用于分析中国大陆30个省级区域的工业生产，并给出了一些启示。
The rapid development in economy of China has intensified the country’s many problems, such as environmental pollution and energy shortage. Thus, establishing a society with resource conservation and environmental harmony, typically reusing the pollution and waste from the industrial production, has attracted attention from both the government and the public in recent years. Data envelopment analysis (DEA) has been widely used in measuring two-stage network structures that constituted with homogenous decision making units. However, previous works failed to take the undesirable intermediate products into account in the two-stage network structures including production system and disposal system. In this study, we build an additive DEA approach to evaluate the efficiency of the proposed new two-stage network structures, and propose a better efficiency decomposition to the individual system. Finally, our approach is applied to analyze the industrial production in 30 provincial level regions in mainland China and some implications are given.
