The purpose of this paper is to analyze the impact of different information source on consumer attitudes toward genetically modified food.

The data used in this study are obtained from a large-scale nationwide consumers' survey in urban China conducted by the China Center for Agricultural Policy, Peking University, in 2020. A descriptive analysis between information sources and consumer attitudes toward GM food was conducted. Based on the collected data, an econometric model on the determinants of consumer attitudes was constructed and used for analysis.

This study shows that the impact of new media is currently no different than that of traditional media, indicating that the media campaign successfully reduced the spread of rumors and misinformation regarding GM food. Moreover, this study also shows that consumers whose main information source regarding GM foods is school hold more positive feelings toward such food.

This study contributes to the existing literature by examining the impact of information source on consumer attitudes toward GM food. To reverse consumers' negative attitudes, China has launched a widespread media campaign since the first decade of the 2000s. Results of this study show that authorities' efforts to manage and surveil new media have yielded the desired outcome.

The purpose of this paper is to examine the dynamic of consumers' perceptions of GM food and explore whether their knowledge of GM technology is associated with a significant change.

This paper presents a meta-analysis of 156 primary studies reporting a total of 225 attitudes toward genetically modified foods. To identify the impact of consumers' knowledge of GM technology, the authors estimate multivalued treatment effects model.

The results of this study show that consumers' attitudes show a U shape during 2001–2022. That is, the rise in opposition to genetically modified foods has been reversed. In addition, this study also shows that the increase in consumers' knowledge of genetically modified technology contributes to their changes in attitude.

This paper is the first study that empirically investigates the dynamics of Chinese consumers' attitude to genetically modified foods, and shows the rise in opposition to genetically modified foods has been reversed, which has important implication for commercialization of genetically modified crops in China.

The purpose of this paper is to try to empirically answer whether the economic benefit of Bt cotton is dying away in China. As the development of the pest resistance and the outbreak of the secondary pest, it was believed that economic benefit of Bt cotton is dying away. And reduction of cotton sown area in recent years had been considered as one of the consequences. This study empirically estimates the impact of Bt cotton adoption on cotton sown area.

This paper uses regression techniques based on provincial level data. In addition, the fixed-effects model is used to control the impact of those time-consistent variables. Finally, several scenarios are estimated for the robustness of the estimation results.

This study shows that the adoption of Bt cotton has positive impact on cotton sown area. On the other hand, the increasing labor cost and decreasing cotton price might be the real reasons behind the decrease of cotton sown area.

This, it is believed, is one of the first studies to empirically answer the impact of Bt cotton adoption on cotton sown area in China, using national representative data.

The purpose of this study is trying to document and examine the impacts of pesticide use on farmers' health. Different from previous studies, the paper is not only going to focus on the visible effect, but also the invisible effect. At the same time, the paper is going to divided the pesticides into highly toxic and low toxic pesticides and estimate their different impacts on farmers' health, respectively.

This paper uses regression techniques based on a farm household survey gathered by the authors in Zhejiang provinces. In addition to a sit‐down interview with 100 households, the authors gave a comprehensive physical examination and a blood examination to farmers who applied pesticides most frequently in each household.

This paper indicates that farmers who spray more pesticides are more likely to have headache, nausea and skin problems. Beside these visible effects, this paper also finds that exposure to pesticides has significant invisible impact on farmers' neurological, liver and kidney systems.

This, it is believed, is one of the first comprehensive studies to give comprehensive physical examination and blood examination to farmers who applied pesticides most frequently in each household.

The purpose of this paper is to investigate factors influencing household food consumption away from home in Beijing by type of food facility and type of meal.

Derived from the Becker's household production and consumption theory, the authors econometrically specified household expenditure function on food away from home. Box‐Cox transformed double‐hurdle models were estimated. The data were collected in 2007 in Beijing China by the authors, using a diary‐based method designed specifically for this study.

Household income, time opportunity cost and other socio‐demographic and economic factors were found to be important determinants of household participation and expenditure decisions for dining out. However, the importance of these factors varied by type of food facility and type of meal. Meanwhile, the estimated elasticities with respect to income were correspondingly higher than those for developed countries, suggesting that the demand for food away from home by Chinese households is still in an upward trend.

To the best of the authors' knowledge, this study is the first to analyze Chinese household food consumption away from home by type of food facility and type of meal. Besides, this study uses an exclusive dataset collected from a seven‐day diary‐based survey. The data include more specific information on food away from home than the Urban Household Income and Expenditure (UHIE) survey data conducted by National Bureau of Statistics of China. The UHIE data were extensively used in previous studies on food consumption in China, but are believed to significantly underestimate food away from home consumption.

The purpose of this paper is to analyze the impact of structural changes in hog production manure management practices.

The data used in this study are obtained from a large-scale nationwide hog producers’ survey in rural China conducted by the Center for Chinese Agricultural Policy, Chinese Academy of Sciences, in 2010. A descriptive analysis between hog manure management and its main determinants was conducted. Based on the collected data, an econometric model on the determinants of hog manure management was constructed and used for analysis.

The results of this study suggest that the scale of hog production has an important impact on the pattern of hog manure management. Moreover, the results from descriptive statistics and multivariate estimation suggest that smaller hog producers are more likely to apply hog manure to their own lands, while larger hog producers are more likely to sell the manure or find other ways to dispose of it.

This study contributes to the existing literature by examining the impact of structural changes in hog production on hog manure management and the environment.
