Climate change, adaptation and inequality: the case of China 

报告人：李郑涛 副教授

报告人简介

    李郑涛博士，浙江财经大学经济学院副教授，荷兰格罗宁根大学博士。主要研究方向为环境经济学，行为经济学。 在《Ecological Economics》，《Economic & Human Biology》等杂志发表文章， 长期担任《Ecological Economics》，《Energy Economics》等杂志的匿名审稿人。

摘要：

    This paper offers a unifying framework for understanding the relationships among climate change, adaptation and inequality by using a nationally representative, longitudinal survey on Chinese subjective well-being (SWB) from 2010 to 2017. Both effects of long run average temperature trend and short run temperature fluctuation within a county across years on Chinese people’s SWB were simultaneously examined. We found the short run high temperature (above 30°C) negatively and significantly impacts Chinese people’s SWB. Furthermore, the short run temperature fluctuation is a more important driver of the effect of climate variation on Chinese people’s SWB than the long run average temperature trend, and Chinese people’s adaptation to high temperature (above 30°C) is very limited. In addition, we found low income people are more likely to lose a flow of subjective well-being relative to rich people due to the short run high temperature fluctuation, and preexisting inequality in China is significantly exacerbated by climate change.

题目三

中国粮食市场政策干预、比较优势与种植结构调整

报告人：王文亭 博士生

摘要：

    本文从粮食生产力布局与比较优势相匹配的视角出发，基于全国层面考察中国主要粮食品种相对比较优势与种植结构的变化趋势，并检验是否根据比较优势原则实现了资源的有效配置。进一步，基于1995~2018年省级面板数据，通过中介效应模型实证分析了2004年以来粮食市场政策干预对粮食种植结构的影响和作用机制。结果表明，粮食种植结构调整在2004年前和2015年后遵循了比较优势原则，而在2004~2015年，种植结构的调整方向与比较优势原则相悖；政策干预对种植结构的影响存在以相对收益为中介变量的显著中介效应，不同粮食作物政策干预的非对称性扭曲了价格激励信号和相对收益，进而导致种植结构调整偏离比较优势，引起资源错配和效率损失，这一现象在供给侧结构性改革后得到明显改善。未来应继续深化市场化改革，根据各地区的相对比较优势调整政策支持力度，发挥政府“有形之手”的积极作用，形成结构合理的粮食有效供给。

题目四

Good Bye Farming: How does Adult Children Migration Affect Land Rental Decision of Parents Left-behind? Evidence from Rural China

报告人：张丽婧 博士生

摘要：

    Over past forty years, China has undergone an accelerated economic development since a series of market-oriented reforms. Combined with urban-prioritized policies, the rapid economic growth in urban areas attracted large amounts of rural labor to migrate and work off-farm. In fact, adult children are the primary group of people migrating out to urban cities for higher income job opportunities and elderly parents being left behind. Facing the fact increase of youth labor out-migrate from rural to urban and simultaneous of aging trend of agricultural labor, elderly parents who are left behind are facing the tradeoff whether participate in land tenancy market after their children migrate. This study develops a theoretical framework from intergenerational transmission to explain how adult children affect land market participation decision of parents and analyze finance intermediary role of remittances in framework. We investigate the impact of adult children migration on land rental participation decision of parents left-behind using two rounds data from Chinese Family Data Base. We find positive adult children migration effects on land renting-out decision of older parents (average age ≧55 years) left-behind. While, it is insignificant for younger parents (average age <55 years) left behind. Furthermore, no effects of adult children migration are found on left-behind parents whether younger parents or elderly parents left-behind in this study. This research provides a novel, intergenerational perspective to understand land-rental behaviors of left-behind parents especially for senior left-behind parents, which can offer further information and speculation on reallocation of land resources along with labor migration flow and aging trend for agricultural labor.
