摘要
剖析中国甘薯区位竞争优势,对优化甘薯区域布局、促进中国甘薯产业在差异化竞争中实现可持续发展具有一定现实意义。基于2011—2019年中国甘薯统计数据,利用评价区域竞争力的相关指标,测算中国各省(自治区、直辖市)的甘薯产业竞争力。结果显示,中国作为世界甘薯生产大国,近年来保持了生产规模的相对稳定和单产水平的总体提升。其规模比较优势区域以四川、重庆、广西和贵州等西南部地区为主,效率比较优势则分布在新疆、山东、京津冀、黑龙江以及江浙等东南沿海一带,而综合比较优势较高的区域则以西南和东南沿海等相关省区为主。中国甘薯产业竞争力提高既受宏观环境和中观上不同区域产业发展差异的影响,也受微观生产经营主体面临产业链不同环节的掣肘。基于此,提出了提升中国甘薯产业竞争力的对策建议,如改善甘薯产业发展的宏观环境、不同区域因地制宜地实施差异化竞争战略、微观生产经营主体需重点弥补各自在产业链中存在的关键短板等。
Analyzing the location competitive advantage of China's sweet potato is of practical significance for optimizing the regional layout of sweet potato and promoting the sustainable development of China's sweet potato industry in differentiated competition.Based on China's sweet potato statistics from 2011 to 2019,using relevant indicators to measure regional competitiveness,the competitiveness of sweet potato industry in various regions of China were measured.The results showed that China,as a major sweet potato producer in the world,has maintained a relatively stable production scale and an overall increase in yield level in recent years.The area of comparative advantage of scale are mainly in southwestern regions such as Sichuan,Chongqing,Guangxi and Guizhou,while the comparative advantages in efficiency are distributed in Xinjiang,Shandong,Beijing-Tianjin-Hebei,Heilongjiang,Jiangsu and Zhejiang and other southeast coastal areas,Regions with higher comprehensive comparative advantages are dominated by related provinces such as the southwest and southeast coastal areas.The improvement of competitiveness of China's sweet potato industry is not only affected by the macro environment and the differences in industrial development in different regions,but also by the constraints from different links in the industrial chain that come from the main body of production and operation.Based on this,countermeasures and suggestions on enhancing the competitiveness of China's sweet potato industry were put forward,such as improving the macro environment for the development of the sweet potato industry,implementing differentiated competition strategies in different regions according to local conditions,and making up key shortcomings in the industrial chain for the micro production and operation entities.
