农村改厕新技术新产品推广应用问题与对策研究

［目的］厕所既是一个国家和地区发展水准和文明程度的体现，也与人民群众的健康息息相关。随着我国农村人居环境整治力度的不断加强，农村改厕新技术新产品不断涌现，加强其市场化研究可为建立农村改厕新技术新产品市场化机制、打赢“厕所革命”攻坚战提供决策参考。［方法］文章基于农村改厕新技术新产品区域适用性分析与各地农村改厕工作推进情况，结合实地调研形成的判断。［结果］我国农村改厕存在政府支持政策体系不完善、新技术新产品研发推广市场导向不足、行业缺乏规范和农户参与意识薄弱等主要问题。［结论］破除农村改厕新技术新产品市场化困境，需要科学合理加大资金支持、搭建新技术新产品市场化平台、构建政产学研协作推进机制、加强农村改厕的规范化管理、鼓励多种形式的社会化服务、加大宣传培训促进市场推广，多措并举建立市场化机制。     

基于三维分形的山东省农户分化及耕地利用异质性分析

研究目的:揭示农户分化的内在机制及其耕地利用异质性,正确引导农户耕地经营行为和可持续利用。研究方法:基于分形理论建立"职业—收入—耕地规模"三维农户分类体系,开展山东省农户耕地利用调研及实证分析。研究结果:(1)农户间耕地利用行为具有差异性,耕地面积较大的兼业户表现出"高投入—低收益"特征,且农户类型存在动态变化的可能性;(2)经济发展水平较高的城市呈现以"高度兼业户"为主要农户类型的"单核心"分化趋势;(3)农户分化过程除大规模纯农户和高度兼业户的"终点"外,还存在对农业依赖较大的兼业户和耕地面积较大兼业户等"中间态"。研究结论:农户分化过程有律可循,应针对性地制定耕地利用政策加以引导。     

The Income and Consumption Effects of COVID-19 and the Role of Public Policy*

We provide empirical evidence on the labour market impacts of COVID-19 in the UK and assess the effectiveness of mitigation policies. We estimate the relationship between employment outcomes and occupational and industrial characteristics and assess the effects on consumption. Seventy per cent of households in the bottom fifth of the earnings distribution hold insufficient assets to maintain current spending for more than one week. We compare the effectiveness of the UK's Coronavirus Job Retention Scheme and of Economic Impact Payments in the US. The EIPs are more effective at mitigating consumption reductions as they have full coverage, depend on household structure and are higher for low-income workers.     

Putting ‘merchants of debt’ in their place: the political economy of retail banking and credit-based financialisation in Germany

Why did household debt in Germany not increase after the year 2000? This article offers a supply-side explanation for this deviant debt trajectory by tracing the historical evolution of retail banking in the German political economy. It argues that at the end of the 1990s and in the light of European Monetary Union, profitability issues and banking fragmentation became severe enough to interrupt the path towards credit-based financialisation as prevalent among other capitalist economies. These factors interacted with a traditional lack of tools and incentives for rapid credit expansion, even though they were renegotiated in the processes of financial liberalisation, internationalisation and innovation. By employing historical-qualitative as well as statistical evidence for the argument, the paper’s contribution becomes twofold. First, it introduces and conceptualises retail banking as a focal point in the analysis of national financial systems and their transformation. Second, it complicates the standard accounts of German non-financialisation and reveals the ‘contested’ character of financial reform.     

农村土地细碎化治理及制度变革启示——安徽省怀远县“一户一块田”的实践探索

土地细碎化是当前我国农业生产的基本格局，也是农业适度规模经营和农业现代化的主要障碍之一。土地细碎化表面上是地块的细碎化。实质上是土地产权的细碎化，而无论是土地流转还是土地整治，都未能从根本上整合细碎化的土地产权。怀远县基于方便农民耕种的需要，在基层大胆创新的基础上，充分发挥集体组织调整土地的功能，通过“三不变、两提倡、一调整”形成了“一户一块田”的耕种模式，有效解决了土地细碎化难题。我国农村土地细碎化治理及制度变革，必须强化集体组织的土地统筹权利和能力，赋予其相应的土地（地块）调整职能，并加强农村基层组织建设；要立足于小农经济为主的基本国情，保护耕作者的利益，为满足现代化小农生产提供服务；既要尊重各地群众的意愿和创造性，也要规范指导，有序推进。     

国有部门与非国有部门的工资差异及影响因素研究

基于CGSS数据，利用Heckman样本选择模型对中国国有部门与非国有部门的工资差异和影响因素进行系统研究。回归结果显示，国有部门员工的教育收益率高于非国有部门，教育收益率与学历水平呈现正相关关系，与非国有部门相比，国有部门中大学本科及以上学历员工的教育收益率更高。工资差异分解结果表明，两部门全样本工资差异中市场歧视占比高于特征差异占比，与全样本相比，大学本科及以上学历员工的工资总差异和特征差异占比更高，系数差异占比更低，说明高学历群体中部门间工资差异更为明显，而且两部门中仍存在较严重的劳动力市场分割和就业歧视问题。因此，政府应努力消除劳动力的流动性障碍，深化国有部门市场化改革，制定更为合理的工资机制，以促进中国经济的持续健康稳定增长。     

A Gendered Model of the Peasant Household: Time poverty and Farm Production in Rural Mozambique

Using insights from a case study on the allocation of labor in subsistence households in Mozambique, this study develops a conceptual framework for examining linkages between time poverty and farm production. An unexpected event such as a health crisis increases the demand for labor provided by women, thus making them more time poor. The model and numerical simulations show that a deterioration in a woman's time constraint will have an adverse effect on agricultural output of the household. This occurs because most women respond to an increase in household work by reducing their work hours on the farm and by reducing their leisure time. The latter outcome is expected to have a negative effect on women's physical and mental health, which will then cause a decline in their productivity on the farm.     

Three Short Stories of Progressive Institutional Change

The process of institutional change is a fundamental theme in institutional economics. There are multiple avenues for forging institutional change — policies, laws, cultural norms, social movements, and social practices. I analyze three examples of progressive institutional change. While there are many to choose from, the three short stories focus on: (i) accounting for measures of housework and care work in GDP; (ii) transforming legal values through adoption of marriage equality in the United States; and (iii) interrogating the fresh-tomatoes food supply chain in order to achieve a penny-a-pound more in earnings for migrant field workers. Each of these examples of progressive institutional change involves changing values, a cumulative process.     

A novel methodology for designing a household waste collection system for insular zones

This paper addresses the problem of designing a household waste collection system for rural insular areas using a barge for transportation, based on a novel mixed integer programming model that simultaneously integrates decisions of waste collection sites selection within the islands to be served, visit schedule for each selected collection site, and multi-period vehicle routing. An application to a real-world instance consisting of small rural islands located in the south of Chile shows the effectiveness and complexity of the model, along with the advantages of using a waste compactor instead of transporting the waste using bins onboard a barge.     

Tourism expenditure patterns in China

Using China’s urban household survey data for 2002–2009, this study compares the impacts of the socio-economic and demographic characteristics of urban household expenditure on tourism in different age cohorts. The life cycle age profiles of group-tour and non-group tour expenditures are obtained by decomposing total household expenditure. The results show that the age profile of total tourism expenditure is hump-shaped, which conforms to consumers’ income discretionary expenditure cycles. The age profile of group-tour expenditure is hump-shaped whereas that of non-group tour expenditure is S-shaped, corresponding to the substitution of group and non-group tours as children grow older. The implications are discussed in the context of tourism marketing with a view to providing useful segmentation information for tourism decision makers.
