农户行为层面生态环境问题研究进展与述评

采用文献回顾法和归纳法,从研究内容、研究视角、研究区域、研究方法和手段、数据获取等方面对农户层面生态环境问题的相关研究进行梳理与分析,最后总结了现有研究存在的问题,并探讨了未来农户层面生态环境问题研究发展的方向。主要结论如下:(1)研究内容涉及农户行为引起的农业环境问题类型、农户行为的生态环境效应、农户环境保护行为与生态建设行为、农业环境保护政策创新等方面;(2)研究视角主要包括以农业生产行为决策者农户为中心内生视角和以农户需求与以农户行为为出发点的外部视角,研究区域主要集中在经济发达地区;(3)在研究方法方面,早期主要是采用一般描述、定性分析和"事前"估计法,近年来"事后"计量模型的研究逐步增多,趋于多样化和综合性;(4)数据获取主要是农户问卷调查和参与式农村评估方法;(5)今后研究应加强农户行为对环境影响的定量评价与跟踪研究、农户环境保护响应决策机制、基于农户行为的环境政策设计等方面的研究,在数据获取方面,应将地理空间信息与问卷调查、社会经济状况结合起来,并进行农户行为与生态环境变化的长期跟踪。     

Relationships among healthy lifestyle beliefs and body mass index in urban China

Consumption is a major driving force in China's economy. The consumer society is particularly emerging in the more urbanized and affluent regions in China. Given the rise of consumerism on the one hand, and the rise of overweight and obesity on the other, this study explored whether the proliferating consumer culture is a threat to the traditional health culture in China. The lifestyle‐oriented approach used in this study does not confirm a straightforward relationship between an upward trend in Chinese with (economic) assets to join the consumer society and a downward trend in health interest among urban Chinese. The result that the rise of the consumer society is not directly accompanied by a devaluation of health issues does not imply that lifestyle research is of no use. On the contrary, this paper successfully identified four dimensions of health‐related lifestyle for urban China, namely Food‐health Belief, Perceived Knowledge, Health Careless and Group Conformity. This result is informative with respect to the complexity of sociocultural factors influencing the increasing prevalence of overweight and obesity.

ANTI-POVERTY EFFECTIVENESS OF THE MINIMUM LIVING STANDARD ASSISTANCE POLICY IN URBAN CHINA

Since its inception 15 years ago, the Minimum Living Standard Assistance (MLSA) has served as a last resort for China's urban poor. Using national household survey data, this study provides updated evidence on the participation rate, receipt amount, and anti-poverty effectiveness of MLSA. Families eligible for MLSA make up 2.3 percent of the urban population, but only about half of them are actual beneficiaries. City MLSA generosity and household entitled benefit amount both positively correlate with participation rate and household receipt amount. MLSA lowers the poverty rate somewhat, but substantially reduces the poverty gap and severity for its eligible participants. Nevertheless, the poverty reduction role of MLSA is restricted by its partial coverage and delivery. Consequentially, poverty remains a serious problem for MLSA's target population. The anti-poverty effectiveness of MLSA can be strengthened by full coverage and delivery of benefits and by paying special attention to disadvantaged subgroups.
