| Abstract: |
| In order to promote the high-quality and sustainable development of China′s mariculture industry, this paper constructed a theoretical model based on the influence mechanism between science and technology innovation, technology promotion and total factor productivity of mariculture industry, selected relevant data and variables in the coastal areas engaged in mariculture from 2006 to 2018, empirically examined the impact of science and technology innovation on the total factor productivity of mariculture industry and the role of technology promotion in the impact mechanism, and put forward development suggestions. The results showed that science and technology innovation played a significant role in promoting the total factor productivity of mariculture industry and technology promotion. Technology promotion played a significant role in promoting the total factor productivity of mariculture industry, and had an intermediary effect on the impact mechanism of science and technology innovation to improve the total factor productivity of mariculture industry. The empirical test results were robust after the substitution variable method and the supplementary variable method. In the future, China′s development of mariculture industry should further enhance the ability of science and technology innovation and technology promotion. |
