Abstract:

Sericulture is an important industry supporting the revitalization of mountainous villages in Sichuan Province. The purpose of this study is to promote the sustainable and high-quality development of sericulture industry in Sichuan. Taking the sericulture industry on the city scale as the research object, this study analyzes the four development elements of sericulture industry, which are development foundation, development potential energy, policy support and environmental capacity. In view of the contradiction that ‘the area of mulberry gardens in Sichuan Province has increased year by year in recent years, but the cocoon output and its proportion in the total output of the country gradually decreased’, five development types of sericulture industry on the city scale are determined by K-means clustering method. The results show that: Class I area, including 12 non-production areas such as Chengdu, has large environmental capacity, but its development foundation is weak, the production area is decreasing year by year, and the policy support is insufficient; Class II area, including one main production area Mianyang, has a good development foundation and strong policy support, but the environmental capacity is small and the production area is decreasing year by year; Class III area, including five general production areas such as Panzhihua, has a certain development foundation, large environmental capacity and sufficient potential energy, but the policy support is weak; Class IV area, including Liangshan Prefecture and Yibin, has excellent development foundation, sufficient potential energy, strong policy support, but small environmental capacity; Class V area, including one main production area Nanchong, has a good development foundation and strong policy support, but small environmental capacity and insufficient development potential energy. Based on the above research results, this study suggests that Class I should be gradually eliminated from the sericulture industry planning in Sichuan, Class II and Class V should stabilize the production area and strengthen the potential energy, Class III should strengthen policy support and guide planting, and Class IV should optimize the structural of the whole industrial chain.

Key words: sericulture industry, development potential energy, policy support, environment drive, industry planning
