The rapid development of China’s digital economy has promoted the digital transformation of Chinese society and become a new driving force for China’s social development. Furthermore, increasing farmers’ income is the central task of China’s “three rural issues” project, and the integrated development of primary, secondary, and tertiary rural industries is an important way to revitalize rural industries and broaden farmers’ income channels, so it is very important to promote the integrated development of rural industries. In the context of the rapid development of China’s digital economy, it is of great significance to study how the digital economy promotes the integration of rural industries. Therefore, this study analyzed how China’s digital economy promotes the integration of rural industries by using the panel data and regression models of 30 provinces (municipalities and districts) in China from 2011 to 2021. The results show that (1) there is a significant positive relationship between the development level of the digital economy and the level of rural–industrial integration and that the development of the digital economy promotes the process of rural–industrial integration; (2) intermediary effect analysis shows that as the digital economy promotes rural–industrial integration, scientific and technological innovation levels and rural human capital are important intermediary channels; and (3) spatial analysis shows that the development of the digital economy can not only promote the integration of rural industries in the province but also have a positive spatial spillover effect on neighboring provinces. Therefore, it is necessary to create a good atmosphere for the development of the digital economy, constantly promote the development of the digital economy, pay attention to scientific and technological innovation and rural talent training, and promote the integration and coordinated development of the digital economy and rural industries between regions in order to improve the level of rural–industrial integration and contribute to the rural revitalization strategy.

China’s shrimp farming industry has experienced significant growth in recent years. With such a development, some major constraints linked to the industry’s sustainable development have emerged. This paper aims to present an overview of China’s shrimp industry over the last two decades, with special attention to farm-raised shrimp both in marine and inland waters. Documentary research on its recent evolution was carried out based on data collected from China Fishery Statistics Yearbooks 2003 to 2022 coupled with data from FAO. Findings indicated that there has been an upward trend in China’s total shrimp production over the last 20 years, with a growth rate of 120%, representing an average annual growth rate of 4.3%. The observed higher shrimp production was driven by expanded shrimp aquaculture production, with major species dominated by the Pacific whiteleg shrimp (litopenaeus vannamei), the black tiger shrimp (Penaeus monodon), the Chinese shrimp (Penaeus chinensis), and the Japanese prawn (Penaeus japonicus). Challenges associated with the intensification of the production and the driven environmental deterioration need to be properly addressed. First, the shrimp farming industry should be practiced while considering both environment and ecosystem protection. Applying such an organic farming principle presupposes some practices for addressing the existing issues threatening the sustainable growth of the industry. To that end, there is a need for innovative techniques that should be strengthened. Second, possible solutions to shrimp disease problems, namely prevention, early diagnosis, and various control techniques, should also be developed and improved, with an emphasis on the former. In addition, encouraging the use of good-quality feed in appropriate quantity and form is also of paramount importance. It is thus worth noting that further policies need to focus on promoting a large range of ecological shrimp aquaculture technologies that should be encouraged among farmers.

With the continuous improvement in people’s living standards and the change in consumption concept, green food is favored by more and more consumers. Consumer repurchase behavior is a necessary condition to activate the market, expand the consumption scale and stabilize the continuous growth of the market. Repurchase intention is the most direct factor affecting consumers’ green food repurchase intention. Therefore, it is necessary to study consumers green food repurchase intentions. This study collects data from 303 consumer surveys on green food consumption to explore the impact of consumer satisfaction with consumption experience on green food repurchase intention and further explore the mechanisms and influence boundaries. The results show that (1) consumer experience satisfaction positively affects green food repurchase intention; (2) consumer experience satisfaction can improve consumers’ green food repurchase intention through consumer perceptions of social value, green self-efficacy and warm glow; (3) the higher the degree of consumer inertia, the stronger the influence of green self-efficacy and warm glow on consumers’ green food repurchase intention; and (4) the higher the degree of consumer subjective norms, the stronger the influence of consumer perceived social value, green self-efficacy and warm glow on the consumer’s green food repurchase intention. This study provides a new perspective and theoretical framework for promoting consumers’ green food repurchase intention, and it may have certain theoretical significance and practical impact on green food market growth, sustainable carrying of the ecological environment and high-quality development of agriculture.

The sustainable development of the aquaculture industry is of great significance for national food security within the context of increasing consumer demand, scarce land resources, and continuous ecological and environmental deterioration. China is a major shrimp farming country. It is crucial to investigate the spatiotemporal variations in the characteristics of shrimp aquaculture for the stability and sustainable development of China’s shrimp aquaculture industry, as well as to explore an optimization strategy for the spatial layout of this industry. Existing research mainly focuses on the fluctuations in shrimp production and their influencing factors, while studies on the spatiotemporal variations of shrimp aquaculture and their influencing mechanisms are few. In this study, we analyzed the patterns of spatiotemporal variation in shrimp aquaculture in China and further explored their influencing factors using standard deviational ellipse and Geodetector, based on China’s shrimp aquaculture production data from 2003 to 2020. The results show that (1) there has been a steady upward trend in shrimp aquaculture production in China over the past 18 years, with a growth rate of 128% and an average annual growth rate of 5.2%; (2) the spatial distribution range of shrimp farms has expanded, showing a zonal distribution pattern from the northeast to southwest, and the center of the shrimp aquaculture industry has generally shifted southward; and (3) the level of development within the fishing industry, labor quantity, and per capita income are the main factors affecting the spatial distribution variability of shrimp aquaculture. The degree of influence of each different factor on spatial distribution of shrimp aquaculture varied temporally.

The rapid development of marine aquaculture since the 1980s has resulted in significant changes in the seafood supply chain of China. First, the unprecedented increase in the scale of seafood output brought about extensive changes in the structure and methods of seafood production. Second, significant expansion in the seafood processing sector occurred as a result of the increase in the scale and variety of processed seafood, such as surimi (ground fish meat) and its products. There also was a concomitant upgrading of phytosanitary criteria. Third, diversity in new occupations within the distribution channel emerged with a proliferation of new wholesale markets. Fourth, there was expansive growth in the seafood trade as cultured seafood and its products were added to the export trade, and the quantity and value of seafood exports increased rapidly. Fifth, a broader variety and increased quantity of chilled and fresh seafood became available to consumers in addition to traditional frozen seafood. Interestingly, there was an apparent adjustment of taste preferences of Chinese consumers to different types and species of seafood on an ongoing basis. Additionally, seafood maintained steadier prices in comparison to other high protein commodities such as meat, eggs, and milk. However, there remain problems related to market stabilization, the lack of power of fishermen and fish farmers in market transactions, and especially issues of seafood safety, that may hinder the improvement and development of the seafood supply chain, and require the Chinese government to take effective measures.
