Abstract
This paper examines the impact of expressway development in China on enhancing dietary quality among residents and explores its operating mechanisms. Theoretically, expressway is posited to improve dietary quality by augmenting residents’ income and optimizing local market accessibility. Empirically, we utilize dietary consumption data from the China Health and Nutrition Survey spanning 12 regions from 1997 to 2011 to estimate dietary quality among Chinese residents. Meanwhile, we integrate provincial expressway data to investigate the effect of expressway on dietary quality. Findings indicate that expressway development significantly improves the dietary quality of residents, primarily through increasing income and market accessibility. Heterogeneity analysis reveals that the influence of expressway on dietary quality varies across urban and rural areas, different income brackets, and diverse dietary patterns. Expressway has a larger effect on urban, middle-and high-income households, and those with a more balanced diet, compared to rural, low-income households, and individuals with less balanced diets. Specifically, general roads, social insurance, and dietary awareness help to promote dietary improvement effect from expressway among rural, low-income households, and individuals with less balanced diets, respectively. This research contributes novel theoretical insights that facilitate dietary structures transformation among Chinese residents.
期刊介绍：
Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches.
Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet.
From this perspective, the journal covers the following areas:
Global food needs: the mismatch between population and the ability to provide adequate nutrition
Global food potential and global food production
Natural constraints to satisfying global food needs:
§ Climate, climate variability, and climate change
§ Desertification and flooding
§ Natural disasters
§ Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production
§ Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production
The sociological contexts of food production, access, quality, and consumption.
Nutrition, food quality and food safety.
Socio-political factors that impinge on the ability to satisfy global food needs:
§ Land, agricultural and food policy
§ International relations and trade
§ Access to food
§ Financial policy
§ Wars and ethnic unrest
Research policies and priorities to ensure food security in its various dimensions.
