Abstract:

Based on the estimation of the net mariculture carbon sink and the coupling index between carbon sink and economics, this study discussed the coordination between economic and environmental performance of mariculture in China. By using of both national and provincial data from 2008 to 2016 of China, this study came to the conclusions as following: although the net amount of mariculture carbon sink nationwide remained between 430 to 490 thousand tons per year, the environmental and economic performance got out of sync. Each year during 2009-2014 was in either strongly or weakly decoupling status except for 2010 when it came to increasingly coupling, which means that the growth of mariculture of China still relied on scale expansion in this period. Negatively decoupling relationship appeared from 2015 to 2016, which means that an efficient market mechanism was needed to transfer ecological profit into monetary revenue despite the preliminary achievements of the strategy of Marine Ecological Culture. Results differed between provinces. The net carbon sink kept negative in Hebei, Hainan, and Tianjin from 2009-2016. Guangdong, Fujian, Shandong, and Liaoning have made the greatest contribution to the net carbon sink. The majority of years showed decoupling in Fujian, Zhejiang, and Jiangsu, meaning the economic subsystem outbalanced environmental subsystem of mariculture in these provinces. The relationship between net carbon sink and mariculture increase did show a negatively decoupling trend, revealing the environmental subsystem preceded economic subsystem in these two provinces. The mariculture systems were basically balanced in Guangdong and Guangxi. Therefore, the key points of healthy development of marine fishery of China are to accelerate the conversion of the driving power of growth, to build a carbon sink market for marine fishery, and to optimize the allocation of marine spatial and producing resources.
