我国生猪产业生产重心的时空特征及其驱动因素研究
Research on spatiotemporal characteristics and driving factors of production center of gravity in Chinese pig industry
摘要
Abstract
The article aimed to explore the spatiotemporal characteristics and driving factors of the production center of gravity in Chinese pig industry.According to panel data of 13 major pig producing provinces in China from 2001 to 2022,a production center model was used to analyze the characteristics of the shift of production center in Chinese pig industry.A spatial Durbin model was constructed to analyze the spatial spillover effects and driving factors of production center changes in Chinese pig industry.The results showed that the production center and resource endowment center of Chinese pig industry are moving towards the northwest direction.There were significant spatial autocorrelation and positive spatial spillover effects in the production of Chinese pig industry.The driving factors for the change of production center in different pig production areas varied.Among them,precipitation,the number of provincial-level and above scientific and technological innovation platforms,and the contribution rate of agricultural scientific and technological progress had a strong driving effect on potential growth areas,while the key development areas are greatly affected by temperature,transportation density,grassland resource allocation,the number of provincial-level and above scientific and technological innovation platforms,and the contribution rate of agricultural scientific and technological progress.Therefore,the article put forward suggestions to expand the scale of pig farming industry,improve industry concentration,optimize the production space layout of the pig industry,drive the development of the pig industry in surrounding areas,implement differentiated pig industry quality and incremental strategies,and promote the comprehensive development of pig industry in various regions,in order to provide reference for pig industry production.关键词
