Effect of 2008's Beijing Olympic Games on environmental efficiency of 268 China's cities

This paper mainly investigates how 2008's Beijing Olympic Games affects environmental efficiency of China's cities. First, we evaluate environmental efficiency through metafrontier directional distance function (DDF), and compare environmental efficiency in different region from static and dynamic perspectives. We also analyze the different treatment of before Olympic Games, during Olympic Games, after Olympic Games on different groups. We find that TGR in the east is the highest, which indicates that environmental production technology in the east has relatively less difference than other three regions. During Olympic Games positively affected environmental efficiency in Beijing, which negatively affected on environmental efficiency under metafrontier in neighbor cities. After Olympic Games positively affected environmental efficiency in Beijing and co-host cities, however, which has insignificant effect on environmental efficiency in neighbor cities. We try to propose some policy implication. First, it is import to develop high-end industry and lengthen value chain of China's secondary industry. Furthermore, it is necessary to improve environmental threshold of FDI and attract clean FDI, which can decrease environmental pollution. Last, China will host 2022 Winter Olympic Games. It is important to use more environmental-soundly building material, and increase clean renewable energy public bus, which can promote green Olympic Games. (C) 2017 Elsevier Ltd. All rights reserved.
