摘要

燃煤火力发电厂（CTPP）排放的悬浮颗粒物（SPM）会导致呼吸道疾病。然而，在CTPP的效率评估中，这一点并没有得到应有的重视。这项研究通过将悬浮颗粒物纳入印度CTPP的基准测试工作，为文献做出了贡献。在这样的研究中，关于污染产生技术的理论假设或评估工具的选择可能会影响CTPP的排名。为了得出稳健的推论，我们对两种替代的微观经济方法（联合技术和副生产技术）和两种类型的数据包络分析工具（图-双曲线和方向距离函数）进行了比较研究，这些工具应用于印度CTPP的两个代表性样本。结果表明，印度CTPP的效率中等。技术假设或数据包络分析模型的选择不影响CTPP的排名。所有权和工厂负荷系数在决定低效率方面发挥着至关重要的作用，这些因素的影响在各个模型中保持稳定。JEL分类：C61、D22、Q40、Q50

Efficiency of Indian Thermal Power Plants and Suspended Particulate Matter: Findings Across Technological Assumptions and DEA Models

Suspended particulate matter (SPM) emissions from coal-based thermal power plants (CTPPs) cause respiratory illness. However, this has not been given its due importance in the efficiency assessment of CTPPs. This study contributes to the literature by incorporating suspended particulate matter in the benchmarking exercise for Indian CTPPs. In such a study, the theoretical assumptions regarding pollution generating technology or the choice of evaluation tool may impact the ranking of CTPPs. To draw robust inferences, we present a comparative study of two alternative microeconomic approaches (joint and by-production technologies) and two types of data envelopment analysis tools (graph–hyperbolic and directional distance function) applied on two representative samples of Indian CTPPs. Results indicate that Indian CTPPs are moderately inefficient. Choice of technological assumption or data envelopment analysis model does not impact the ranking of CTPPs. Ownership and plant load factor play vital roles in determining inefficiency, and impacts of these factors remain stable across models. JEL Classifications: C61, D22, Q40, Q50

期刊介绍： Studies in Microeconomics seeks high quality theoretical as well as applied (or empirical) research in all areas of microeconomics (broadly defined to include other avenues of decision science such as psychology, political science and organizational behavior). In particular, we encourage submissions in new areas of Microeconomics such as in the fields of Experimental economics and Behavioral Economics. All manuscripts will be subjected to a peer-review process. The intended audience of the journal are professional economists and young researchers with an interest and expertise in microeconomics and above. In addition to full-length articles MIC is interested in publishing and promoting shorter refereed articles (letters and notes) that are pertinent to the specialist in the field of Microeconomics (broadly defined). MIC will periodically publish special issues with themes of particular interest, including articles solicited from leading scholars as well as authoritative survey articles and meta-analysis on the themed topic. We will also publish book reviews related to microeconomics, and MIC encourages publishing articles from policy practitioners dealing with microeconomic issues that have policy relevance under the section Policy Analysis and Debate.
