摘要The China State Council issued the “the regulation on livestock production pollution” in October, 2013. The key content of the Regulation is to close the livestock farms near water resources directly. Using a county-level panel data, the research adopted the DID method to evaluate the impact of the regulation on the structural change between livestock sector and crop sector in agricultural sector. Baseline results show that the regulation has brought a 2.35% decrease of ration that livestock sector accounts in agriculture. However, we currently did not find significant effects for the ratio that crop sector accounts for agriculture.

 

题目二How do the composition of asset portfolios affect consumption of households——evidence from China based on micro data

主讲人:司凡,博士生

摘要To accelerate the transformation of economic growth modes from investment-driven to consumption-led, the rising wealth in China and its influence on consumption deserve special attention from both policy makers and academic researches. Based on household data from Chinese Family Database and China Household Finance Survey, this paper aims to investigate how asset portfolios affect consumption of households. It is proved that the composition of asset portfolios, asset levels and asset price changes significantly affect consumption of households. As expected, both increased asset price and past assets exert positive impact on household current consumption by contrast with negative impact of future assets. Meanwhile, there are larger wealth effects in rural areas; in particular, assets with attributes of consumer goods have larger impacts on non-durable consumption in western and central areas; by comparison, in eastern developed areas assets with attributes of investment goods have larger impacts on non-durable consumption. Considering the importance of assets on consumption, integrated financial system is required to create conditions for promoting property income and facilitating financial capacity of rural households, which is necessary for policy formation of Chinese economic transition.


题目三:消费者选购生鲜果蔬支付意愿及其影响因素的研究

主讲人:黄好,博士生

摘要本地属性是消费者研究领域近年来非常热门的产品属性,消费者选购本地产品的一个重要原因是其较高的新鲜程度,本文探讨消费者对不同新鲜程度的樱桃番茄的支付意愿及其影响因素,以此为生鲜产品的生产者和经销商制定产品战略提供参考。本文基于实物随机n价拍卖实验和理化实验结果展开分析,得出以下结论:(1)消费者非常关注生鲜农产品的新鲜度,但分辨新鲜程度的能力有限;(2)此外,消费者知识和性别消费者对支付溢价存在显著影响。


题目四:农村土地调整与土地确权:一个多维度检视

主讲人:郑淋议,博士生

摘要:坚持农村土地承包关系稳定并保持长久不变是中国农村土地制度的基本方针,如何处理人口变动与土地承包的关系成为农业生产经营面临的现实难题。二轮承包以来,土地调整屡禁不止,土地确权艰难推进,全国土地调整的发生率仍高达43.1%,土地确权的完成度只有61.43%。土地调整受到广泛的支持,希望调整土地的农民达到61.23%,土地确权被普遍看好,88.95%的农民认为土地确权会给他们带来好处。究其原因,主要在于土地调整和土地确权影响效应的相互嵌套。具体表现在:在土地集体所有制下,一方面,非正式制度嵌入的自治传统和集体成员权的法理隐喻事实上满足了土地调整的发生条件,而且在现阶段土地调整的正面效应可能大于负面影响,它能够维持土地社会保障功能、减轻农业生产效率损失和促进社会公平,而土地确权却难以有效解决承包期内时间线上的动态公平问题;另一方面,土地调整并非万能,它也可能导致土地细碎化、土地投资减少、农民经营预期不稳等弊端,而土地确权恰好能够通过明晰产权、确定权属来增加土地投资和提高土地资源利用效率。进一步定量分析发现,现阶段,作为正式制度的土地确权一时难以替代表征为非正式制度的土地调整,土地调整仍具有一定的合理性,土地确权时同步进行土地调整更有助于公平和效率目标的实现,在土地确权完成后的五年之内也是土地调整合理的窗口。
