我国水产品出口贸易隐含碳生产率演变特征及驱动因素分解
Evolution characteristics and driving factors of embodied carbon productivity in China's aquatic products export trade
摘要
Abstract
Under carbon peaking and carbon neutrality goals,studying embodied carbon emissions and its productivity of China's aquatic product export trade can not only accurately assess the impact of aquatic products trade on the environment but also holds significant importance for promoting the sustainable development of China's aquatic product trade.This paper used the input-output model to measure the embodied carbon emissions of China's aquatic products export trade from 2007 to 2021,taking into account the carbon sink emission reduction effect of some aquatic products,and further constructed the embodied carbon net productivity index of aquatic products export trade.Subsequently,this study analyzed the evolution characteristics and differences in country-specific flows of the embodied carbon productivity of China's aquatic product export trade using the kernel density estimation method.With the help of LMDI method,it decomposed the embodied carbon productivity of China's aquatic product export trade into three dimensions:energy production efficiency,foreign trade dependence,and export value-added effect,to study its driving factors.The results show that:(1)The embodied carbon productivity of China's aquatic products export trade as a whole exhibits the characteristics of"'slight decrease-continuous increase".There are certain differences among countries,which show a trend of"'substantial narrowing-continuous expansion-basic convergence".And the embodied carbon productivity of China's aquatic product export trade to South Korea has been higher than that of other trading partner countries year by year.(2)The carbon emission level in China's aquatic product trade has achieved significant reduction,but energy conservation and emission reduction is primarily focused on the reduction of direct energy consumption,while the indirect energy-saving and emission-reduction effects is not obvious.(3)Energy production efficiency is the main driving factor for the embodied carbon productivity of China's aquatic product export trade;the export value-added effect plays a weak driving role;and the export trade dependence has a negative inhibitory effect on the embodied carbon productivity of aquatic product export trade.Therefore,improving energy production efficiency,adjusting the export structure of aquatic products,and actively establishing a new development paradigm of the fishery industry with domestic market as the mainstay are important paths to enhance the embodied carbon productivity of China's aquatic products export trade.关键词
