Digital Road is the new direction of rural revitalization, and the digital economy empowers rural revitalization as a new driving force for the sustainable development of agriculture and rural areas. Currently, the studies on the digital economy and rural revitalization are focused on a certain dimension and lack research on the influence mechanism of the digital economy driving rural revitalization and their spatial effects under the same framework. Based on the panel data of 31 provinces in China from 2013 to 2021, the paper explores the influence mechanism of rural revitalization driven by the digital economy and their spatial spillover effects by using the benchmark regression model, intermediary effect model and spatial Durbin model, and draws the following conclusions: (1) Digital economy can significantly promote rural revitalization. (2) Digital economy can significantly promote the revitalization of rural areas by transforming industrial structure and rural entrepreneurship. (3) The development of the digital economy will significantly promote the revitalization of villages in the region and the level of rural revitalization in neighbouring areas. After the endogenous treatment and robustness test, the above conclusions remain valid.
Under the scenario of the complex external environment and internal structural changes in agricultural development, exploring the synergistic relationship between agricultural green efficiency (
AGE
) and agricultural economic resilience (
AER
) can offer a new path for fostering sustainable regional agricultural development. This paper fills the research gap in the interaction between efficiency and resilience in agriculture. We explore the synergistic mechanism of the two based on the perspective of sustainable development, providing a reference for constructing a synergistic theoretical system of AGE and AER. Moreover, we apply the Haken model to the field of the agricultural economy and scientifically evaluate the level of AGE and AER synergy in Northeast China from 2010 to 2020. Finally, we analyze the influencing factors of AGE and AER synergy in Northeast China from three dimensions: economic, social, and natural. The results show that AER is dominant in the AGE-AER synergistic system. The synergy level of AGE and AER in Northeast China is mainly in the higher and advanced synergy stages, with obvious spatio-temporal differences and insufficient inter-regional radiation effects. Social factors are the main factors of spatial differentiation of AGE and AER synergy.
The construction of an ecological civilization is a strategic idea proposed based on the conditions of different countries and the laws governing social development. It is a new way to promote harmonious coexistence between humans and nature. Therefore, exploring the evolution characteristics and influence of ecological civilization in China is helpful for the country’s future development. This study uses the pentagon model, panel threshold regression model, and spatial analysis tool to explore the law of space-time differentiation and analyze regional coordination and ecological civilization construction in 31 provinces, cities, and autonomous regions in China from 2000 to 2018. During the study period, the construction of ecological civilization in China generally fluctuated; the spatial differentiation pattern of the eastern region was more developed than that of the central region, which was more developed than that of the western region. The regional coordination degree decreased in the order of east >central >northeast >west, and the degree of coordination in provinces and cities gradually shifted and finally accumulated to be reflected in the economy and environment in 2018. The most important factor affecting the development of ecological civilization was determined to be scientific research, followed by air quality and government information disclosure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
