Strengthening urban–rural linkages (URLs) has been proposed by UN-Habitat within the framework of ‘Sustainable Development Goals (SDGs)’ to narrow down urban–rural differences via shaping new urban–rural relationships. Like URL, the aim of urban–rural integration (URI) has been promoted by the Chinese government since 2019 to address existing urban–rural divides. This concept underlines the ‘rural revitalisation’ strategy and emphasises a two-way flow of urban–rural development factors. Introducing and upgrading ‘appropriate’ rural industries is crucial to stimulate and facilitate the circulation of urban–rural development factors. This research studied three neighbouring villages, situated in urban–rural interface areas in Huangyan-Taizhou, China, each driven by different types of small industries supported by URI. It analyses the impact of small rural industries on the flow of development factors between urban and rural areas. The results showed that small-scale rural industries have been enhanced URL by decreasing urban–rural differences by creating new job opportunities to attract an in-flow population, increasing investments, and upgrading public services and infrastructure. Indigenous industries demonstrated lower profitability but exhibited greater resilience compared to industries linked to global production chains and rural tourism. Thus, this study demonstrates the imperative to carefully consider the opportunities and potential risks associated with pursuing strategies of URI through rural industry development. By providing empirical insights from URI projects in China, this study contributes to theoretical and policy dialogues concerning the concepts of both URL and URI by exploring the localization of SDGs. Furthermore, it offers valuable practical knowledge and experience for other global regions confronting similar challenges to urban and rural development.

Urban–rural integration (URI) has emerged as a crucial strategy to bridge urban and rural disparities and promote more sustained urbanisation paradigms in China and abroad. The urban–rural interface, where urban and rural spaces and daily activities are closely intertwined, reflects the complex and evolving dynamics of this integration, serves as a focal point for studying URI, and requires unique considerations in spatial planning. This study focuses on the scale of the county level and the basic spatial units for spatial planning practice in China to examine different types of urban–rural interfaces and their URI dynamics at a county level. By taking Linqu County as a case study region, land use data from Landsat remote sensing datasets were collected every 5 years from 2000 to 2020 to support the analysis of changes in the urban–rural interface. Three dimensions of land mixed-use features were employed, including the area and density, edge and shape, and aggregation and dispersion of the construction land in the region. When combined with the proportion of rural land use, the urban–rural interfaces were identified using the entropy method. This study then employed spatial analysis, the standard deviation ellipse method, and spatial autocorrelation to recognise URI dynamics, and three driving forces were identified and further analysed to support suggestions for county-level spatial planning. This research empirically enriches the understanding of the urban–rural interfaces and URI dynamics of Linqu, China. The methods and suggestions derived from the empirical study can offer potential solutions to promote URI in China and enhance urban–rural linkage in the global context to reach more sustained development.

Rural industrialisation in China, which has historically been restricted by urban–rural dual development policies, has been largely encouraged since the Rural Revitalisation Strategy released in 2018. Industrialisation has deeply influenced socio-spatial evolution by providing job opportunities and promoting the construction of infrastructure and public services, accelerating the two-way flow of urban–rural factors in rural areas. However, this may lead to social and spatial issues, such as social inequalities and unsuitable living conditions, to some extent. This research aims to investigate how the socio-spatial evolution of rural areas was influenced by rural industrialisation and the two-way flow of urban–rural factors. The cherry planting industry and an active “industrial centre”, Yuezhuang Village, in Linqu County, Shandong Province, China, were selected for the empirical study. This research analysed the evolution of the cherry planting industry, the formulation of rural social networks, and the spatial adaptation of the two using mixed qualitative and quantitative methods, followed by a discussion on the current rural planning policies in China. The results show that the cherry industrial chain largely extended the planting areas, and the categories of land use generally increased in Yuezhuang Village over the 30 years studied. The average output value per mu (mu is unit of area measurement used in China, where it is officially standardised. It corresponds to 1/15 of a hectare, or about 666.67 m²). In 2021 was 25 times larger than that in 1996. The population involved in industrial activities increased to over 5000 people countrywide from the initial 17 households. The results also show that urban–rural factors, such as capital, population, techniques, and information, rapidly accelerated in the annual peak season of the cherry industry. This research indicates that small-scale, characteristic, and traditional agriculture could become one of the main driving forces in urban–rural integration and may contribute to sustainable and inclusive rural communities and urban–rural partnerships. This provides the theoretical mechanism of socio-spatial interaction in rural industrialisation in China based on the empirical case study.
