贵州省辣椒产业区域集群竞争力及时空演化特征分析

Analysis of Regional Competitiveness and Research of the Spatio-temporal Characteristics of Pepper Industry Cluster in Guizhou Province

基于2018-2022年贵州省9个市(州)辣椒产业相关统计数据,采用区位商系数(LQ)和集中系数(CC)、规模优势指数(SAI)、效率优势指数(EAI)与综合优势指数(AAI)等方法,研究了贵州省区域辣椒产业集群度与竞争力,并通过马尔科夫链进一步探究贵州省区域集群竞争力时空演化特征,以期为提升贵州省辣椒产业集群竞争力并使之成为乡村振兴支柱产业提供参考依据。结果表明:1)从集中化程度看,遵义市、毕节市、铜仁市和黔南州辣椒产业具有集群优势;从竞争力角度看,这4个地区的AAI值均大于1,集群竞争力显著,其中,遵义市集群竞争力最强,但4个地区集群竞争力较强的成因不同。2)贵州省区域辣椒产业集群竞争力在时空演化上具有稳定性,存在一定地理范围的“弱俱乐部趋同”现象,区域集群竞争力维持中等和高水平状态不变的概率最大。最后从加快产业现代化建设和发挥区域竞争优势等方面提出发展建议。

Based on the relevant statistical data of pepper industry from 9 Cities(Prefectures)in Guizhou Province from 2018 to 2022,the location quotient coefficient(LQ),concentration coefficient(CC),scale advantage index(SAI),efficiency advantage index(EAI)and comprehensive comparative advantage index(AAI)were adopted to explore the competitiveness of regional pepper industry cluster in Guizhou Province,and the spatio-temporal characteristics was further carried out through Markov chain,in order to provide reference for enhancing the competitiveness of the pepper industry cluster in Guizhou Province and making it a pillar industry for rural revitalization.The results showed that,1)Zunyi,Bijie,Tongren and Qiannan prefecture had cluster advantages in terms of centralization.Their regional cluster competitiveness was strong,because their AAI values were all greater than 1,among which the cluster competitiveness of Zunyi was the strongest.Also,the reasons for the strong competitiveness of the four regional cluster were different.2)The competitiveness of regional pepper industry cluster in Guizhou Province was stable in terms of spatiotemporal evolution,and there was a phenomenon of‘weak club convergence’to certain geographical areas.The probability of maintaining the status of medium and high level was the largest.Finally,suggestions were proposed to promote the development of pepper industry cluster from the perspectives of accelerating industrial modernization,leveraging regional competitiveness,et al.
