Abstract:

In the face of the new development situation, the traditional mode of fishery production no longer can meet the requirements of the current social transformation. The low-carbon development of the fishery industry is an inevitable choice for its sustainable development in China, a practical need to ensure the national food security and promote the income increase of farmers (fishermen) and economic and social development, and is of great significance for fundamentally promoting the supply side structural reform of China’s marine fisheries. Based on the input-output model and the extended Kaya identity, this study examined the changing trend and structural characteristics of embodied carbon emissions in China’s fishery production system, and decomposed the driving factors of the embodied carbon emissions. The results show that: (1) Embodied carbon emission of fishery production system in China as a whole showed a trend of rising, slightly decreasing, rising again, and falling, the primary fishery sector always had the highest embodied carbon emissions, but the embodied carbon emissions of the secondary and tertiary fishery sectors increased gradually. (2) Fishery capture and aquaculture, processing, and circulation are the main sectors of the embodied carbon emissions in the fishery industry. The embodied carbon emission level per unit output value of the three fishery sectors and the 12 sub-sectors all showed a downward trend, among which the embodied carbon emission level per unit output value of fishery drug, aquatic transportation, and fishery construction sub-sectors was the highest, which had a great impact on the embodied carbon emissions of the fishery industry. (3) The fishery economic growth and general fishery technological progress have positive impact on the embodied carbon emissions of the industry, and fishery economic growth is the main factor that drives the growth of the embodied carbon emissions. Fishery population, fishery economic structure, and low-carbon fishery technology have a certain degree of restraining effect to the embodied carbon emissions. Low-carbon fishery technologies are the biggest factor to restrain the embodied carbon emissions of fisheries in China. Therefore, adjusting the structure of the fishery industry, changing the mode of fishery growth, and improving the application level of low-carbon fishery technologies are the key to effectively restraining the embodied carbon emissions and realize the low-carbon development of the fishery industry in China.
