Food safety is a very important topic in China. We investigate Chinese consumers’ preferences and willingness to pay (WTP) for food traceability using a choice experiment. Given that consumers’ trust in the food system may affect their preferences and WTP, we also assess the interaction between consumers’ trust in government’s supervision of food safety and food labels and consumers’ preferences for traceable food products. Using data collected from a choice experiment on Fuji apples in a face-to-face survey in six Chinese cities, the results show that (i) consumers are willing to pay for traceable food but their valuations can differ upon the degree of their trust in government’s supervision of food safety and food labels; (ii) consumers are willing to pay for traceability with strong evidence of preference heterogeneity; (iii) government is not the most trusted safety inspection and certificate authority as found in prior studies using animal food products in China.  相似文献

Abstract

It is thought that policies aimed at encouraging the accumulation of human capital in less productive regions can constitute a key factor in development. However, the effectiveness of this policy depends in large part on each region's capacity to give returns to human capital. The aim of this article is to demonstrate the existence of substantial spatial variations in private and aggregate returns to human capital, indicating that development policies based on stimulating the accumulation of education differ in effectiveness. Results for the Spanish regions suggest that regional variations in social returns are greater than those in private returns.  相似文献

Regional integration: an empirical assessment of Russia   总被引:1,自引:0,他引:1  
Using a statistical model of commodity trade, we quantify the evolution of regional economic integration within Russia during 1995–1999, and explore potential determinants of this evolution. Our integration measure exhibits rich regional variation that, when aggregated to the national level, fluctuates substantially over time. In accounting for this behavior, we draw in part on theoretical models that emphasize the potential role of openness to international trade and regional disparities in income in threatening economic integration. Controlling for a host of additional regional- and national-level variables, we find a strong negative correspondence between openness to international trade and internal economic integration.  相似文献

China is currently the largest CO2 emitter in the world and demonstrates one of the highest levels of energy consumption. The sustainable consumption behavior has increased in China, especially in urban cities. Some clear evidence of this includes food purchasing behavior. Recent studies have also suggested that considering full product information transparency, consumers are willing to pay premium prices for products. With this in mind, sustainable consumption must still be facilitated by related policies, regulations, and tools. This study focuses on sustainable consumption behavior in China and collects and analyzes the literature from the last decade (2007–2017) on the topic. In so doing, it highlights new trends and research topics against the background of circular economy development. The method of systematic review is applied. The review is categorized into several main groups: national policies and regulations, the green awareness of consumers, the definition of related concepts, the barriers between sustainable consumption and the circular economy, and the indicators for circular economy assessment in China. Future research directions are discussed. Furthermore, future challenges are addressed from three perspectives: sustainable consumption facilitating the circular economy, “cradle‐to‐cradle” practices, and the link between the European Union and China. This is a fundamental study in the research domain of sustainable consumption behavior. It provides added value that benefits both academic researchers and decision makers. It also sheds light on the further study of sustainable consumption behavior in China from a macroeconomic perspective.  相似文献

This article explores and theorizes the ways in which urban space and political contestations are mapped onto each other. The ethnography illustrates the multifaceted transformations in a notoriously secularist neighborhood of ?stanbul, Te?vikiye, as it first turns into a high‐consumption locality in the post‐1980s, then into a high‐conflict urban space in the new millennium on the arrival of Muslim high‐spenders, particularly headscarved women. Aiming to fill the gap left by the absence of spatial analysis from political science and political sociology, I argue that the urban neighborhood becomes central for political contestation when both government and opposition fail to protect and secure liberties and rights. Now that devout Muslims are integrated into highly contested urban sites and share bourgeois lifestyles, ordinary people act in defense of their ‘sphere’ of freedom and privacy. This new territoriality is largely symptomatic of increasing fears of losing freedom, privacy and social status. This spatial defensiveness is reinforced by people's decreasing trust in, and increasing demands from, the state for the protection and security of their rights and liberties. My overarching argument is that exclusive attention to the bipolar clash between devout Muslims and secularists under the rubric of ‘neighborhood wars’ obscures multipolar conflicts around the discontents stemming from authoritarianism and democratization.  相似文献
