由于污染物排放的不同,以及异质减排技术的不同,经济生产系统的结构和模型设计需要考虑这些差异。本研究在考虑不同类型污染物减排技术异质性的基础上,首次提出了一种基于网络松弛的生产系统效率低下模型(SBM)。然后,利用该模型对我国工业生产系统的非效率进行了研究,分析了经济生产和污染物治理两个阶段的非效率。此外,还讨论和比较了与SO2(NOx)产生(排放)有关的低效的区域分布。结果表明,只有在两个子阶段同时联合减排NOx才是可行的,而协同减排似乎是有限的。
Due to the difference in pollutants discharged, along with heterogeneous abatement technology, the structural and model design of the economic production system needs to consider these differences. This study first proposes a network slacks-based model (SBM) to address the inefficiency of the production system after considering pollutant abatement technology heterogeneity for different kinds of pollutant. Then, we employ the model to study the inefficiency of the Chinese industrial production system, analyzing the inefficiency in the stages of economic production and pollutant treatment. Furthermore, the regional distribution of inefficiencies concerning SO2 (NOx) generation (emission) are discussed and compared. The results show that only the joint reduction of NOx in two sub-stages simultaneously is feasible, and the synergistic pollutant reductions seems limited.
