社会资本视角下“以购代捐”精准扶贫模式研究 ——基于凉山彝族自治州的实证分析

以凉山彝族自治州在精准扶贫过程中,为破解贫困地区“孤岛效应”,探索“以购代捐”扶贫模式为例,基于社会资本导向 的反贫困治理策略,分析“以购代捐”扶贫模式的理论内涵、演进路径、模式创新等,提出“以购代捐”正面临,物流投入滞后,影 响农产品品质;质量标准缺乏,制约农产品价格;质量检测缺位,食品安全堪忧;产品价格缺乏优势,长期执行易陷入行政摊派 等现实问题,为了完善“以购代捐”精准扶贫模式,建议：一要调动贫困农户生产积极性,保证农民“爱种（养）”;二要合理兼顾帮 扶单位的利益,让对口帮扶单位“爱吃”;三是政策措施要简单易行,让行政主管部门“爱扶”。     

基于《巴塞尔Ⅲ最终方案》的弹性杠杆率监管研究

弹性资本充足率监管加刚性杠杆率监管存在机理性缺陷。弹性资本充足率监管会影响刚性杠杆率监管的效果,刚性杠杆率监管也不能体现杠杆累积在时间维度和空间维度风险的变化。若引入弹性杠杆率缓冲,刚性杠杆率监管加弹性资本充足率监管的机理性缺陷就可以避免。因此,有必要实施弹性杠杆率监管,杠杆率的弹性化程度与银行的系统重要性程度相对应。     

资本下乡：进入模式选择及其影响因素

进入模式是经济组织配置资源的重要手段。以工商资本对农户经营活动的控制权程度为依据,将工商资本投资农业的进入模式划分为“松散型”、“半紧密型”、“紧密型”三种类型。利用对广东、湖北、江苏以及云南四省151个投资主体的调查数据,采用有序逻辑回归模型分析生产因素、市场因素、制度因素以及生产技术传递能力对工商资本投资农业的进入模式选择的影响。结果表明：耕地资源优势越弱,工商资本投资农业选择紧密型进入模式的可能性越高;市场潜力越大,越倾向于选择紧密型进入模式;非正式制度越不利,选择紧密型进入模式的可能性越低;生产技术的传递能力越弱,越倾向于选择紧密型进入模式。     

Social capital in Croatia: measurement and regional distribution

By using partial least squares path modeling, this paper develops a complex index of social capital, selects Croatia as the case for testing and validating the index, and investigates the regional distribution of social capital. The social capital index is defined as a complex hierarchical structured construct of third-order with social trust, participation, and civism as its core dimensions. The main results indicate that civism is the most important cause of social capital followed by active participation and social trust. As far as the regional distribution of social capital is concerned, there are statistically significant differences across the Croatian regions. Although the lowest or below the national average level of social capital and its dimensions can be mostly found in the least developed regions (with the exception of the capital), the highest level of social capital and its particular dimensions is not achieved in the most developed regions.     

When is brokerage negatively associated with economic benefits? Ethnic diversity,competition, and common-pool resources

There is a growing body of literature positively linking dimensions of social capital to economic benefits. Yet recent research also points to a potential “dark side” of social capital, where over-embeddedness in networks and the pressures associated with brokerage are hypothesized to constrain actors, having a negative effect on economic outcomes. This dichotomy suggests that context is important, yet the overwhelming majority of existing empirical evidence stems from socially homogenous populations in corporate and organizational settings, limiting a broader understanding of when and how context matters. We advance this discourse to a socially fragmented, ethnically diverse common-pool resource system where information is highly valuable and competition is fierce. Merging several unique datasets from Hawaii's pelagic tuna fishery, we find that network prominence, i.e., being well connected locally, has a significant, positive effect on economic productivity. In contrast, we find that brokerage, defined here as ties that bridge either structurally distinct or ethnically distinct groups, has a significant, negative effect. Taken together, our results provide empirical support to widespread claims of the value of information access in common-pool resource systems, yet suggest that in ethnically diverse, competitive environments, brokers may be penalized for sharing information across social divides. Our results thus contribute to an emerging theory on the fragile nature of brokerage that recognizes its potential perils and the importance of context.     

It is risky business: can social capital reduce risk-taking behaviours among disadvantaged youth?

This study addresses the gap in the research for sound multidimensional assessment of social capital and its relationship with risk-taking behaviour among youths living in disadvantaged communities. Social capital and adolescent risk-taking outcomes were studied cross-sectionally in 1371 secondary students living in two disadvantaged communities within Australia. First, a multidimensional measure of social capital was developed and tested using confirmatory factor analysis. Then, the associations between social capital and a range of youth risk-taking behaviours were examined using structural equation modelling across five-year groups (Grades 7–12). With a few exceptions, higher levels of social capital and belongingness within the school and community were generally associated with decreases in smoking, alcohol and drug consumption, and physical violence. Some outcomes were more strongly associated with family and peer social capital, while others associated more with neighbour and community social capital, indicating that attempts to build social capital need to be targeted across the whole community. This study supports the notion that social capital can be measured empirically and is beneficial in alleviating many of the detrimental health outcomes commonly associated with risk-taking behaviours during adolescence.     

Network domains in social networking sites: expectations,meanings, and social capital

This paper examines why the use of social networking sites (SNSs) leads to different results in cultivating bridging and bonding social capital for different groups of people. Based on in-depth interviews of 45 university students in Hong Kong, I find that Mainland Chinese students studying in Hong Kong actively use SNSs for seeking practical information about offline matters, and they obtain substantial enacted support from other Mainland students of the same university through SNS use. As a result, they accumulate both bridging and bonding social capital. Local Hong Kong students, however, use SNSs mainly for social information seeking and are only able to accrue limited bridging social capital through SNS use. Drawing on the theory of network domains, I argue that the different offline network structures in which students are located – namely, homogeneous and closed networks versus heterogeneous and open networks – explain this difference. Students with closed offline networks have defined expectations of online ties; they think of their online activities as practical and leading to real changes in their status among peers. Those with open networks have indefinite expectations of their online audience; thus, they interpret online activities differently, thinking of them as recreational, and they are playful in their online behaviour. These different outcomes of online activities consequently lead to diverse results in social capital accrual.     

“农转非”、人力资本回报与收入不平等——基于分位数回归分解的方法

随着中国城镇化进程的推进，越来越多的农村户籍人口实现了身份转换，成为制度认可的新市民。本文利用中国综合社会调查（CGSS）数据发现，即使户口状况相同，"新市民"与"老市民"之间依然存在一定的收入差距。分位数回归及其分解的结果显示，"农转非"人群在劳动力市场上仍受到制度性或非制度性歧视，且歧视程度随着分位数的变化呈现倒U型趋势。同时，"农转非"人群内部也存在较大的差异，歧视降低了自致型"农转非"人群相较于城市原居民的禀赋优势，而外致型"农转非"人群则面临人力资本劣势与就业市场歧视的双重压力。

上海国有创投企业与深圳、苏州、广东等创投公司基本上同时起步,但近年来实力差距拉大。碉研认为,上海应通过集团化发展整合现有的国有创投企业,建立上海科技金融集团,并通过机制创新,解决国资管理与市场化经营的冲突问题,使上海国有创投业成为服务上海科技创新战略、新兴产业发展和转变经济发展方式的有力抓手。     

A Quantitative Estimate of the Dominant Position of Public Ownership in China and Trends in Its Development

以不同生产资料所有制的经营性资产价值量作为衡量主次地位的边界标准，估算第一产业公有制与非公有制的资产规模及其比重变化，并在前人估算的基础上，延伸估算第二和第三产业两种所有制的资产规模及其比重变化。结果发现：截至2012年，中国三次产业经营性总资产约为487．53万亿元，其中公有制经济的资产规模是258．39万亿元，占53％；第二、三产业非公有制经济占增加值和就业规模的比重分别为67．59％和75．20％。这表明，公有制资产仍占主体，非公有制经济贡献占优，中国社会主义基本经济制度充满活力，从而为我国社会主义初级阶段的所有制改革和坚持“两个毫不动摇”的政策提供了理论依据。
