| Abstract: |
| Since the entry of 21st century, with the evolution of industrial space pattern of mulberry silkworm industry featured by "the shift of mulberry silkworm from the East to the West", great changes have taken place in main production provinces of mulberry silkworm and their comparative advantages. Based on the analysis of industrial concentration and industrial comparative advantages, this paper compared the comparative advantages of China′s silkworm industry′s main producing areas, and analyzed the factors affecting the shift of the comparative advantage of main production areas of mulberry silkworm in China. The results showed that (1) The concentration of silkworm cocoon industry in China showed a downward trend first and then an upward trend from 2003 to 2015. (2) The silkworm industry in Guangxi, Zhejiang, Chongqing, Yunnan, Shaanxi and Sichuan provinces had significant scale advantages (SAC > 2). The advantage of production efficiency in Zhejiang province, a big traditional silkworm industry province, had declined significantly. The comprehensive advantage of Guangxi and Yunnan provinces had been continuously improved, and the industrial production had obviously shifted to the western and central regions. (3) The formation and change of the comparative advantage of the main producing areas of silkworm industry in China was influenced by resources, economy, market, technology, ecology and policy. We should strengthen the construction of silkworm industry chain in Western China, strengthen the macro control of silkworm industry, speed up technological innovation, reduce production costs, improve the comprehensive development level of silkworm industry, and consolidate and promote the development of new major silkworm production areas with comparative advantages such as Guangxi and Yunnan. |
