互联网被认为能够给弱势农户的绿色生产转型带来更多技术红利，但这却与偏向性技术进步理论相悖。从理性忽略的视角，基于山东省1015份农户调查数据，利用内生转换probit模型分析了互联网对农户病虫害综合治理（IPM）技术采纳的影响及其原因。研究表明：（1）互联网虽有效促进了农户IPM采纳，但并未真正给弱势农户带来更多影响，较大的选择偏差导致弱势农户的技术红利被高估；（2）技术信息获取渠道差异导致农户对互联网信息的理性忽略程度存在差别，这是互联网影响异质性的重要原因；（3）对强关系网络信息渠道的过度依赖使弱势农户容易陷入信息茧房，对互联网信息产生理性忽略，因而难以被互联网信息所影响。要更好地发挥互联网对弱势农户IPM采纳甚至绿色生产转型的促进作用，不仅需要推动互联网农业技术信息服务的适老化，还应激励善于利用互联网的农户积极分享外部信息，引导弱势农户走出信息茧房。

供应链可追溯性的构建能够对食品安全问题进行溯源，因此对于降低食品安全风险来说非常重要。此外，它能够帮助监管者了解食品安全风险发生的供应链环节，并能够对上游农业企业的经济性动机掺假行为产生威慑。本文聚焦于中国水产品供应链，试图通过构建批发市场经营户、养殖户和政府三方的博弈模型和使用大规模的水产品批发市场实地调研数据，分析经营户可追溯采纳行为。该实地调研数据涵盖了浙江和湖南两省所有存在水产品交易的批发市场，具体来说，包含76家批发市场和763个经营户的信息。理论和实证研究的结果表明，批发市场经营户之间采用可追溯性与食品安全抽检强度、经营户个人的被抽检经历和风险意识密切相关；此外，在私营市场中，抽检强度对经营户的产品可追溯性采纳的影响要强于国家/集体所有权的市场。本文提供了关于中国水产品可追溯性发展的情况，更为重要的是，发现了可能影响批发市场经营户的产品可追溯性的因素，以期为相关政府部门促进水产品供应链的可追溯性提供建议。

Climate extremes, characterized by droughts and floods, have become one of the major constraints to sustainable improvement of rice productivity.  Variety choice, considered as one of the main adaptation measures, could help farmers reduce yield loss resulting from these extremes.  Based on a three-year panel survey of 1 080 Chinese rice farms in major rice producing provinces, we assume Hicksian neutral technology and employ an IV regression to estimate the average treatment effect (ATE) on rice yield for adopting stress tolerant variety, and find that farmers who adopted the stress tolerant variety on average increased rice yield by 15.5% in comparison to the non-adopters.

Food safety issues constitute an international topic discussed by many scholars. Although there is an extensive body of literature on comparisons of food safety control practices across different governance structures, these studies have been conducted mainly in terms of qualitative and descriptive analysis. In addition, little attention has been given to family farms. This study addresses the food safety control practices adopted by firms with different governance structures in China. Food safety control is expressed by the following aspects, i.e., pollution-free, green, organic, and/or geographical indication products certification, establishment of production records, and pesticide residue testing. Three types of governance structures that engage in agricultural production are distinguished: farmer cooperatives, agricultural companies, and family farms. The food safety control practices of various governance structures are investigated based on a database that comprises 600 vegetable and fruit enterprises in Zhejiang, China. The results show that (1) pesticide residue testing is adopted by the most firms, followed by products certification, and production records are adopted by the fewest firms, and (2) agricultural companies adopt more food safety control practices than family farms, while farmer cooperatives adopt the fewest food safety control practices. Governance structure features of a cooperative in terms of ownership, decision-making, and income distribution are the main reasons for the low level of food safety control in the cooperative.

In recent years, the Chinese government has highlighted the importance of adopting hog safety/quality traceability, and a growing amount of research continues to entice firms to adopt traceability systems. In this study, a survey was conducted on a sample of pig slaughtering and processing firms in Zhejiang, China through personal interviews and emails. The aim of this study was to examine the determinants of firm behavior on the implementation of voluntary traceability systems with more stringent standards and controls than those of the mandatory system in China. The results revealed that motivation based on product quality improvement, capital ability and role perception (business type) had significantly positive relationships with a firm’s voluntary traceability. Other incentives, such as operation improvement, recall risk reduction, reduced occurrence of safety issues, and technical strength were not found to be supportive in our study. This study provides an opportunity to better understand the determinants of firm behavior on voluntary traceability, particularly in light of the fact that some Chinese firms are facing the threat of criminal action for the use of illegal additives and the abuse of Clenbuterol. Policy recommendations on encouraging the implementation of pork safety voluntary traceability by hog slaughtering and processing firms are also discussed.
