中国特色社会主义制度自信：基本依据·价值意蕴·实现路径

中国特色社会主义制度是立足世情、国情、民情和党情建立起来的制度体系。从历史选择到制度实践构成了我们在新时代夯实制度自信的基本依据；从共同富裕到人的全面发展彰显了制度自信特有的价值意蕴。站在新的发展阶段，既需要大胆借鉴古今中外制度建设的有益成果，又务必坚持在实践基础上以理论创新推动制度创新，以制度借鉴、制度实践和制度创新进一步坚定制度自信。     

Responsibilisation,social work and inclusive social security in Finland

ABSTRACT

In this article responsibilisation in social work is studied by analysing two Finnish state-level policy documents (called final report and research report) which concern a current activation initiative called inclusive social security (ISS). It is asked how social workers and clients are constructed as responsible subjects in these documents. Responsibilisation refers to the advanced liberal mode of governmentality, which aims to strengthen citizens’ abilities to self-governance through various techniques that include the intertwined elements of surveillance and empowerment. It is demonstrated that the policy documents construct the social workers’ and the clients’ responsibilities partly in different ways. The final report leads activation to be based on shared responsibility and social work to be more community-based, whereas the research report strengthens more individual-based responsibility of clients and social workers. For the clients, the interpretation of ISS based on shared responsibility would probably be less stigmatising and paternalistic than the one based on individual responsibilities, i.e. approaching long-term unemployed citizens as being personally ‘at risk’ and thus a justified target group of individualised techniques for activation. For social workers and clients, future activation appears to be a wide mix of different techniques, moral expectations and possible ways of being a responsible subject.     

Does a universal non-contributory social pension make sense for rural China?

China’s pension reform during the past three decades has allowed a majority of China’s population to be covered by a pension scheme. Of particular note has been the New Rural Pension Scheme (NRPS), a voluntary programme introduced starting in 2009. One goal of our analysis is to assess that pension scheme, using a variety of sources of information including data drawn from recent (2013 and 2015) nationwide China Health and Retirement Longitudinal Surveys (CHARLS). Our analysis involves an exploration of differences between the generosity and structure of the NRPS and other pension schemes currently in place. We also explore the feasibility of reforming the current “quasi-social pension” component of the NRPS by substituting a universal non-contributory social pension pillar. In connection with our assessment of the NRPS, we note the unusually low benefit levels for rural China.     

Who Should Pay for Interdependent Risk? Policy Implications for Security Interdependence Among Airports

We study interdependent risks in security, and shed light on the economic and policy implications of increasing security interdependence in presence of reactive attackers. We investigate the impact of potential public policy arrangements on the security of a group of interdependent organizations, namely, airports. Focusing on security expenditures and costs to society, as assessed by a social planner, to individual airports and to attackers, we first develop a game-theoretic framework, and derive explicit Nash equilibrium and socially optimal solutions in the airports network. We then conduct numerical experiments mirroring real-world cyber scenarios, to assess how a change in interdependence impact the airports' security expenditures, the overall expected costs to society, and the fairness of security financing. Our study provides insights on the economic and policy implications for the United States, Europe, and Asia.     

Security Investment in Contagious Networks

Security of the systems is normally interdependent in such a way that security risks of one part affect other parts and threats spread through the vulnerable links in the network. So, the risks of the systems can be mitigated through investments in the security of interconnecting links. This article takes an innovative look at the problem of security investment of nodes on their vulnerable links in a given contagious network as a game‐theoretic model that can be applied to a variety of applications including information systems. In the proposed game model, each node computes its corresponding risk based on the value of its assets, vulnerabilities, and threats to determine the optimum level of security investments on its external links respecting its limited budget. Furthermore, direct and indirect nonlinear influences of a node's security investment on the risks of other nodes are considered. The existence and uniqueness of the game's Nash equilibrium in the proposed game are also proved. Further analysis of the model in a practical case revealed that taking advantage of the investment effects of other players, perfectly rational players (i.e., those who use the utility function of the proposed game model) make more cost‐effective decisions than selfish nonrational or semirational players.     

中国农村研究的主体回归与方法论创新

21世纪以来,中国农村治理研究陷入了本土化与主体性双重困境,中国农村社会基础的深度转型,农村研究方法的缺陷以及大规模村庄研究的局限,要求中国农村研究回归深度的村庄研究,尊重农民主体性。在回归村庄研究的方法论上,文章认为要突破国家政权建设理论等研究视角的局限,把市场化这一变量纳入分析视野中。村庄主位、农民主体、市场化过程同国家宏观治理体系的互动逻辑,应该构成后中国农村治理研究时代的主要内容。     

试论投资基金的治理结构

投资基金的治理结构包含三个层次,即基金的各方当事人权利义务的制度安排、基金内部约束机制、外部市场压力及监管制度。针对我国基金治理结构目前存在的问题,可通过引入独立董事制度、将基金经理的报酬机制与公司的经营业绩挂钩、增强外部市场的竞争压力等途径,使之逐步完善。     

Urban cultivation in Accra: an examination of the nature, practices, problems, potentials and urban planning implications

The literature on urban farming in Sub-Saharan African cities reveals that most studies have been conducted in Eastern, Southern and Central African cities. A few have focused on West Africa, including Sierra Leone, Guinea Bissau, and Cameroon. In Ghana there is a paucity of information on urban farming. The purpose of this paper is to examine the status of urban cultivation in Accra, Ghana's capital, reviewing existing research, and to present new empirical findings on urban cultivation emphasizing on its history, nature, practices, problems, potentials and urban planning implications.     

信息时代国际传播的控制:从管制到治理

以数字化和网络化为标志的信息技术革命使国际传播环境发生了很大变化,也使得民族国家的传播管制面临挑战,而把治理的理念引入国际传播领域,有助于探索在信息技术革命条件下国际传播管理的新途径。国际传播控制从管制到治理,实际是对国际传播秩序的改造和完善:从参与的主体看,承担维持国际传播秩序任务的既有政府组织,也有非政府组织、跨国公司、私人企业、利益集团和社会运动团体等;从治理内容看,于侧重意识形态之外,又加入了保护民族文化、维护本国经济利益等新内容;从范围上说,它已不限于领土范围之内,而是积极参与国际传播领域的合作,以建立有利于完成国内传播控制目的的国际传播环境。     

国有企业治理结构问题产生的根源分析

在我国国有企业改革过程存在的问题中,公司治理结构运作失灵是阻碍国有企业深入改革的最大障碍。本文首先明确了当前认清我国国有企业治理结构问题产生根源的必要性,然后运用委托代理理论和交易费用理论,分析了国有企业治理结构问题产生的根源一一信息不对称、契约不完备、经营者选择机制不合理和股本结构不合理。
