营养干预项目改善了学龄前儿童的营养与发展吗？来自湖南湘西的证据

◇ 摘要：

儿童营养改善是联合国2030年可持续发展议程的重要目标，同时是反贫困政策的重要组成部分。湘西学龄前儿童营养改善试点项目通过提供营养餐补助、开展营养宣教活动和改善幼儿园食堂设备和环境的方式，为改善学龄前儿童营养状况，提升其认知能力与社会情感水平提供实践经验。同时项目实现了与精准扶贫建档立卡贫困户对接、将小农纳入小餐供应链的创新性尝试。本研究采用准实验的方法对项目的效果做了系统评估。评估结果发现，该项目对样本儿童营养不良状况、认知能力和社会情感总体上无显著改善效果，但对特殊群体有显著改善效果。此外，本地化供餐也同时达到了反贫困目标。项目实施后，干预组农户人均年收入显著增加。

Re-examine the Effectiveness of China’s Forest Tenure Reform: Democratic Decision-making and Implementation Mode

◇ 主讲人：

涂冰倩，博士生

◇ 摘要：

Using a panel data covering 286 villages and 3298 households in China, we re-examine the effect of China’s collective forest tenure reform (CFTR) on farmers’ income and provide insight of the policy effectiveness, from the perspective of institutional arrangement and implementation process. The identification relies on a staggered Difference-in-Difference strategy, in which the variations in village-by-village roll-out of the CFTR are explored. Our estimates show that the tenure reform promotes farmers’ income through the channels of tenure security, property rights, and forestland investment. In particular, the democratic decision-making process and the share of certificates issued at the village level contribute to the rise of tenure security. These findings provide supplementary evidence of the impact of tenure reform on individual’s welfare for developing countries.

Purchasing Habits, Age Effects, and Chinese Consumers’ Willingness to Pay for Chilled Pork: Evidence from a Random Nth-Price Auction Experiment

◇ 主讲人：

韩飞，博士生

◇ 摘要：

With Chinese concern on African Swine Fever (ASF), necessary measures have been taken to control the inter-provincial live hog transportation. However, due to the conventional consumption habits, it has been very challenging to replace hot pork with chilled pork in the market. In this study, by recruiting188 participants in Hangzhou, we implemented multiple rounds of random Nth-price auction experiments and measured the participants' perception of quality and WTP for chilled pork under different packaging, and storage temperature & duration labels. Comparing with the physicochemical lab testing data, we verified the existence of quality perception bias of these participants. Consumers with chilled meat consumption habits have higher average WTP, while the elder consumers (1980s generation of China) give significantly higher bids. Selection of emerging purchase channel improves the chilled meat WTP through the channel of branded product purchasing experience. The public sector should further balance the distribution of pork production capacity and support the development of cold chain transportation technology to satisfy the growing demand of consumers (young consumers especially) for high-quality chilled pork.

子女外出距离对农村留守父母心理健康的影响研究

◇ 主讲人：

吴智豪，博士生

◇ 摘要：

在劳动力转移和人口老龄化的双重背景下，子女外出对农村留守父母的心理健康的影响问题日趋突显。本文构建了基于代际支持视角的心理健康理论框架，使用CHARLS数据库2011、2013和2015年家庭追踪调查构造三期面板数据进行实证研究，考察了子女外出距离对留守父母心理健康的影响。结果表明，子女外出距离的增加对留守父母的心理健康产生了显著的负面影响。通过对子女外出距离边际效应的分析，本文进一步发现，留守父母的心理健康水平随着子女外出距离的变远而越来越低。本文从代际支持的视角识别了子女外出距离对父母心理健康的影响并给出了实证依据，研究结论既能够填补当前子女外出距离和父母心理健康关系的空白，同时可以为农村养老保障政策提供科学依据。
