RESEARCH ON THE EVOLUTION AND TREND OF CHINA'S PIG INDUSTRY
The pig industry has always been a significant component of China's agricultural economy,and this study aims to comprehensively analyze the research on this industry,covering various aspects such as its development and current situation,the evolution of research hotspots,and future trends.To achieve this goal,we conducted a quantitative analysis of 1 783 Chinese Core and Chinese Social Sciences Citation Index(CSSCI)papers from the China National Knowledge Infrastructure(CNKI)journal database by using CiteSpace and VOSviewer.(1)The analysis revealed that the research in this field over the past 30 years could be divided into three stages:production capacity improvement,market rectification,industrial adjustment and efficiency improvement,and transition to green and healthy breeding.Additionally,the popularity of research topics such as"pig price"and"pork quality"remained high throughout these stages,with the formation and fluctuation of prices being an important source of high-impact papers.(2)The cooperation network among core authors and institutions in this field was found to be characterized by the"core-periphery"structure,with"geographical guanxi"and"academic guanxi"remaining the primary modes of collaboration.(3)Moreover,the technological innovation capability of an institution was found to impact its level of industrial economy research to some extent.(4)And Prof.Fusheng Chen emerged as an influential scholar in interdisciplinary research on the pig industry.Therefore,to enhance research efficiency,there is a need to strengthen"cross-academic"and"cross-geographical"cooperation among authors and institutions while promoting interdisciplinary cooperation within organizations with technical research advantages to enhance academic influence.In addition,it is necessary to integrate interdisciplinary methods to explore trends such as changes in the pig market structure and social welfare,low-carbon decision-making behavior of organizations,and the revitalization of the pig breeding industry,in addition to continuing to use both qualitative and quantitative research methods.
