Differences of CO2 Emission Performance–Based on Bohai Bay Coastal Zone in China Song Mei, Zhang Shitong, Chang Liyue, Hou Yunbing


The Bohai Bay Coastal Zone is the third largest economic zone in China, with environmental problems having become a constraint to economic growth in this region. This paper first estimates the CO2 emissions in Bohai Bay Coastal Zone from 2012 to 2015. Then it constructs directional distance function and assumes two scenarios to evaluate the regional differences of carbon emission performance in this zone. The result indicates that, first of all, the CO2 emissions intensity in Bohai Bay Coastal Zone is decreasing year by year. And taking energy consumption structure as the indicator can determine CO2 emissions performance more accurately and effectively. Under the two different scenarios, Hebei, Liaoning and Shandong Province have significant differences, which mean that these provinces have great potential in CO2 emissions reduction and energy consumption structure is the key factor. While Beijing and Tianjin City, at the advanced level of CO2 emissions reduction, have shown few differences under the two scenarios. At last, it gives proposal, such as upgrading industrial structure, investing for researches of low-carbon technologies, levying carbon taxes to achieve CO2 emissions reduction goal.
