E-commerce platform-based supply chains have emerged as efficient and widely used channels for the distribution of agricultural products, with low-carbon supply chains capable of reducing the carbon footprint of these products from the initial to the terminal stage, which has led to their increasing adoption by consumers. Based on major e-commerce platforms in China, combined with an extended technology acceptance model, this study examines the factors affecting low-carbon supply chain adoption by agricultural product consumers on e-commerce platforms. The results showed that consumers’ perceived risk, perceived usefulness, and adoption attitude all influence their adoption behavior, with the effect of adoption attitude being the greatest. Furthermore, the effect of perceived usefulness on adoption attitude is stronger than that of perceived risk. Moreover, perceived usefulness is affected mainly by the perceived price, technical utility, green behavior tendency, and subjective norms, whereas the perceived risk is affected mainly by technical utility, information display and dissemination, and green behavior tendency. This study provides valuable insights for e-commerce platforms to better understand the needs of agricultural product consumers, improve market competitiveness, and enhance consumers’ awareness and willingness of adopting low-carbon approaches, which can promote the low-carbon sustainable development of agricultural product supply chains.

Background: The sustainable development of the agricultural product supply chain (APSC) is the key to protecting public health.Methods: This paper explores the sustainable development status of the APSC in three northeast provinces of China from 2007 to 2020 and the development trend in the next 5 years by using the entropy weight—matter-element extension model (MEEM) and autoregressive integrated moving average model (ARIMA), taking into account the background of relatively backward development and the high proportion of agricultural output in these three provinces.Results: According to the research results, the sustainable development of the APSC in Jilin Province is relatively stable, Heilongjiang Province has made considerable progress in the sustainable development of the APSC in recent years, while Liaoning Province has shown a significant downward trend in recent years in the sustainable development of the APSC, despite a strong development momentum in previous years.Conclusions: The findings of this paper can be applied to the governance of APSC in other rural areas with uneven development. The assessment also provides guidance on the quality and safety of agricultural products and public health, and raises the awareness of policymakers on the importance of the APSC.
