Research Status, Hotspots, and Trend Analysis of the Rural Living Environment Upgrade in China from 1992 to 2022: A Bibliometric and Narrative Review Analysis

The rural living environment is the foundation of rural ecology and rural residents’ life, and the quality of the rural living environment is directly related to the green and low-carbon development of rural areas and the physical and mental health of rural residents. This article aims to grasp the current situation and of rural living environment improvement research and its various research hotspots, explore research frontiers and trends, and provide crucial theoretical guidance for rural living environment improvement research by searching and analyzing China’ national knowledge infrastructure database (CNKI). The article adopts CiteSpace6.2 bibliometric software and the narrative review method to analyze 1349 papers on rural living environment upgrading in CNKI from 1992 to 2022. Among them, the narrative review collects and analyzes the relevant information on rural living environment improvement to provide the background and content for the relevant arguments. It is found that (1) the rural living environment governance policies can be divided into four stages, namely, the initial stage, policy exploration, policy enhancement, and policy deepening, with the policy system continuously maturing and the governance content becoming clearer; (2) research hot topics can be summarized as research on the connotation and governance model of the rural living environment, research on development status, research on effective evaluation and influential factors, and research on treatment model and technology involving interdisciplinary integration development; (3) the rural living environment upgrade research history can be divided into three periods: before 2004, which was the start-up stage, thus the number of publications was relatively small, and core topics included the transformation of rural toilets and rural domestic sewage treatment; 2004–2017, which is the expansion stage, thus the total amount of literature is increasing yearly, and the research topics are gradually enriched; after 2018, which is the the mature development stage, further clarifying the key tasks of rural living environment upgrades; (4) in the future, it is necessary to keep the focus on research in the four key areas, deepen the research on governance connotation, influential factors, and effect evaluation, explore the typical models of rural living environment construction in China, and provide research guidelines and practical decisions for rural living environment governance.
