By developing a GDMOD model to estimate the environmental externalities associated with electricity generation, this project provides a detailed analysis of the damages and costs caused by different pollutants at varying distances from the Mawan Electricity Plant in Shenzhen, China. The major findings of this study can be summarized that (1) environmental damages caused by electricity production are large and are mainly imposed on regions far away from the electricity plant; (2) air pollution is the most significant contributor to the total damages, and SO2, NO(x), and particulate matter are the three major pollutants with highest damages; (3) the damages caused per unit of particulate,NO(x), and SO2 emissions are much higher than pollution treatment and prevention costs. The research results of this project showed that China needs to have a more effective levy system on SO2, and a more manageable electricity tariff mechanism to internalize the environmental externalities. The results have also implications for pollution control strategies, compensation schemes as well an emission trading arrangements.
通过开发一个GDMOD模型来估算与发电相关的环境外部性,本项目详细分析了中国深圳妈湾电厂不同距离处不同污染物造成的损害和成本。本研究的主要发现可总结为:(1)电力生产造成的环境损害巨大,且主要施加于远离电厂的地区;(2)空气污染是总损害的最重要贡献因素,二氧化硫、氮氧化物和颗粒物是造成损害最高的三大主要污染物;(3)单位颗粒物、氮氧化物和二氧化硫排放造成的损害远高于污染治理和预防成本。本项目的研究结果表明,中国需要建立一个更有效的二氧化硫征税制度,以及一个更易于管理的电价机制,以将环境外部性内部化。这些结果对污染控制策略、补偿方案以及排放交易安排也具有启示意义。
