| Summary/Abstract |
Natural gas is one of the most important clean energy and has played crucial roles in curbing air pollution in developed world. To facilitate the use of natural gas and reduce air pollution by reaching a similar energy consumption structure to the developed world, Chinese government has vigorously constructed natural gas pipeline projects (NGPPs) during the past decades. This paper evaluates the impact of China's NGPPs on air pollution reduction, by using national data of pollutant emissions of over 800,000 firm-level observations from 1998 to 2010. The difference-in-differences approach shows that the introduction of pipeline natural gas reduces sulfur dioxide (SO2) discharge intensity in connected cities by about 22.8%. The magnitude of the reduced SO2 emissions is estimated to be at least 17.41 million metric tons, a size of 7.33% of the total industrial SO2 discharge from 1998 to 2010. We also find that a substitution effect channel that NGPPs facilitate firms to replace fuel coal with natural gas under tightening environmental regulations.

| Summary/Abstract |
This paper examines how international openness influences China's corporate environmental performance. A unique firm-level dataset is constructed by combining two databases: the Annual Industrial Survey and the China GreenWatch Program Rating System. The empirical results obtained from a series of ordered probit models indicate that openness has a positive relation to corporate environmental performance in China. However, the two main market-opening strategies in China, exporting and attracting foreign investment, have different effects on environmental performance. The results reveal that foreign investment plays a substantial and positive role that can support the environmental spillovers in China. However, the effect of exporting is insignificant. The environmental pressure from foreign customers to improve Chinese firms' environmental performance presents a challenge. Our study indicates that China could make environmental quality improvements through increased international openness, as is likely the case for other developing countries.
