中国高端装备制造业自主技术创新效率稳定性及影响因素研究

在全面实施创新驱动发展战略的时代背景下，揭示中国高端装备制造业自主技术创新效率稳定性，测度相关因素的影响强度与方向，对揭示中国高端装备制造业自主技术创新规律，制定其发展策略具有重要指导意义。聚焦中国高端装备制造业自主技术创新效率稳定性及影响因素，采用DEA-Malmquist指数方法和Tobit回归模型进行实证研究，结果表明，中国高端装备制造业自主技术创新效率存在一定波动性，且各细分行业技术创新效率内部稳定性较差，产业自主技术创新效率整体稳定性不高；自主技术创新投入因素和环境影响因素对产业自主技术创新效率的影响具有较高的异质性，其中创新资金投入和人力资源投入对自主技术创新综合效率、纯技术效率及规模效率具有正向影响，而新产品开发投入和企业规模对自主技术创新综合效率、纯技术效率和规模效率的影响具有异质性，政策因素与市场因素分别具有显著和非显著负向影响，外源性创新因素具有显著正向影响，且影响强度较大。在此基础上，提出调整政府对高端装备制造业创新支持模式、加强外源性创新与智力引进等策略建议。

城市低收入保障制度与反贫困的公共政策

城市低收入保障制度实施中“应保未保”的现象较为普遍，低收入保障所需资金的缺口较大，缺乏全国统一的贫困标准使得其随意性很大。解决这一社会问题必须从近期和远期两个目标入手，近期目标是尽快遏制城市贫困人口剧增的势头，防止在深化改革的过程中出现快速增长的新生贫困人口；远期目标是立足最终消除城市贫困现象。     

试论供应链主体的核心竞争力与领导权策略

一条标准的供应链由处于不同环节的供应商、研发商、生产商、分销商、零售商、信息服务商、物流服务商和消费八大主体构成。处于供应链不同环节的不同主体具有不同的核心竞争力。可以通过获得行业内部的竞争优势力争成为供应链成本集成的主导，在供应链多个环节增强核心竞争力，交叉进入多条供应链，以企业集群和行业协会的方式袅与供应链管理等措施，谋求对供应链的领导权和尽可能大的利益回报。     

提高中国企业在国际供应链中的竞争力

随着经济全球化发展,各国企业开始建立起国际供应链,即通过充分利用全球资源来降低生产成本,增强核心竞争力,获取最大利润.随着中国经济的发展和开放程度的加深,跨国公司的国际供应链逐渐向中国延伸,纷纷在中国建立起采购中心、研发基地和生产基地,把中国作为全球资源配置的基地.

Benefits of Downward Earnings Management and Political Connection: Evidence from Government Subsidy and Market Pricing

This paper examines the role of downward earnings management and political connection on the receipt of government subsidies and market pricing of subsidies. Using subsidies data hand-collected from Chinese listed firms over the period 2004–2014, the results show a significantly positive association between downward earnings management and the receipt of government subsidies. The results also reveal that a firm's political connection is conducive to securing subsidies for poor performers, but not for good performers. Market pricing analyses demonstrate that share markets value subsidies positively in general, but the effect is ameliorated in firms conducting downward earnings management. No discernible difference is found between the market pricing of subsidies received by firms with political connections and those without.     

Housing Preferences of Temporary Migrants in Urban China in the wake of Gradual Hukou Reform: A Case Study of Shenzhen

In the wake of the recent announcement by the State Council concerning the provision of public rental housing across China, and the gradual reform of China's household registration system (hukou), this article explores how potential adjustments in government housing policies (namely access to public rental housing) influence the housing preferences of temporary migrants who are currently residing inside the chengzhongcun (urban villages) of Shenzhen. The results indicate that dissatisfaction with rental cost and living conditions in these urban villages are the key reasons for migrants wishing to move into public rental housing if it is offered to them — and not the fact that they are treated differently within the hukou system. Public rental housing is welcomed in particular by newly arriving migrants who live outside the Shenzhen Special Economic Zone (SEZ), and migrants who have decided to remain in Shenzhen for the foreseeable future. By contrast, dissatisfaction with urban villages is the sole contributor to housing preferences for those residing inside the SEZ.     

Credibilistic risk aversion

In the probabilistic risk aversion approach, risks are presumed as random variables with known probability distributions. However, in some practical cases, for example, due to the absence of historical data, the inherent uncertain characteristic of risks or different subject judgements from the decision-makers, risks may be hard or not appropriate to be estimated with probability distributions. Therefore, the traditional probabilistic risk aversion theory is ineffective. Thus, in order to deal with these cases, we suggest measuring these kinds of risks as fuzzy variables, and accordingly to present an alternative risk aversion approach by employing credibility theory. In the present paper, first, the definition of credibilistic risk premium proposed by Georgescu and Kinnunen [Fuzzy Inf. Eng., 2013, 5, 399–416] is revised by taking the initial wealth into consideration, and then a general method to compute the credibilistic risk premium is provided. Secondly, regarding the risks represented with the commonly used LR fuzzy intervals, a simple calculation formula of the local credibilistic risk premium is put forward. Finally, in a global sense, several equivalent propositions for comparative risk aversion under the credibility measurement are provided. Illustrated examples are presented to show the applicability of the theoretical findings.
