选择"责任险方案"投保工伤保险更符合企业利益

(补充)工伤保险是近年来我国商业保险市场的新生事物。在我国产、寿险分业经营的制度下，财产险公司和寿险公司分别从自己的角度推出了适应这个需求的产品。并由此形成了“责任险方案”和“人身险方案”并存的市场供给局面。本文从法定责任转移、纳税优惠以及前瞻性三方面对两种方案进行了分析对比，得出结论：选用“责任险方案”更符合投保企业的利益。

民主政治与社会和谐

社会和谐问题的关键,是搞好以民主法治为中心的国家治理。中国的制度变迁是经济和社会层面的变迁,是自上而下推动的改革型的变迁,在由权力集中到权力分散的制度转型过程中,稳中求进是中国实现社会和谐的经验总结,制度的设计不宜过于完美。民主政治是社会和谐的前提和归宿,是执政合法性的来源,没有民主政治就没有和谐社会。     

自适应聚类视角下学科领域主题分析——以物流学科为例

基于改进关键词重要性和近邻传播聚类算法,提出了一种学科领域主题分析方法,通过词频分析法和作者潜意识行为计算高频关键词权重,借助共词分析和Ochiai系数构建带权重高频关键词相似性矩阵,利用近邻传播聚类算法对学科领域主题进行自适应提取与分析。以CSSCI收录的2015—2019年物流学科领域期刊论文为研究对象,借助新方法对其进行主题分析,研究结果表明:高重要性的关键词不一定是核心主题,核心主题与同一簇内其它成员关键词最为相似。与此同时,近五年物流学科存在“降本增效”“区域物流一体化”“现代物流技术研究与创新”“物流体制改革与产业转型升级”“农村物流与农产品物流”“电子商务与跨境电商”“可持续发展理念”等七大热门主题。     

Does the social security fund help non-financial enterprises to transform from the virtual to the real?

At its 19th National Congress, the Communist Party of China vowed to “strengthen the financial sector’s ability to serve the real economy.” However, many studies provide evidence of the opposite trend, a problematic “transition from the real to the virtual,” among Chinese enterprises. Meanwhile, the investment efficiency of China’s Social Security Fund (SSF), a public fund, attracts much attention. In this context, we use A-share listed companies in China from 2009 to 2018 to study the relationship between holding by the SSF and enterprise financialization. We find that SSF holding significantly inhibits financialization and that this effect is non-linear. Mechanism analysis indicates that SSF holding suppresses enterprises’ financialization mainly by improving their governance. Moreover, SSF holding more strongly inhibits small-scale (vs. large-scale), state-owned (vs. non-state-owned), and non-eastern (vs. eastern) enterprises in China. Furthermore, SSF holding can alleviate corporate value impairment caused by financialization. The conclusions enrich theoretical research and provide empirical evidence that may help regulatory authorities to guide investment by enterprises and prevent financial risks.     

促进共同富裕的税收制度与政策研究

实现共同富裕是社会主义的根本目标,是社会主义优越性的体现.本文首先介绍了共同富裕的内涵,共同富裕是全体人民的富裕,是兼顾公平与效率的富裕.本文进一步阐述了税收制度在促进共同富裕中发挥的积极作用,并结合具体数据进行国际比较,剖析目前我国税收制度在促进收入分配方面存在的不足.我国税收制度在缩小收入差距方面已取得阶段性成效,但仍存在直接税体系不完善、"税收洼地"引发诸多避税风险、税收征管体制面临多重挑战等方面的不足.最后,本文从持续优化税收营商环境,鼓励勤劳创新致富;健全直接税体系,提高税收调节收入再分配的作用;规范地方税收优惠,维护财政收入分配秩序;提升税收征管水平,严厉打击偷税漏税行为四个维度提出了政策建议.     

The nature of the steady state in models of optimal growth under uncertainty

Summary. We study a one-sector stochastic optimal growth model with a representative agent. Utility is logarithmic and the production function is of the Cobb-Douglas form with capital exponent . Production is affected by a multiplicative shock taking one of two values with positive probabilities p and 1-p. It is well known that for this economy, optimal paths converge to a unique steady state, which is an invariant distribution. We are concerned with properties of this distribution. By using the theory of Iterated Function Systems, we are able to characterize such a distribution in terms of singularity versus absolute continuity as parameters and p change. We establish mutual singularity of the invariant distributions as p varies between 0 and 1 whenever . More delicate is the case . Singularity with respect to Lebesgue measure also appears for values such that . For and Peres and Solomyak (1998) have shown that the distribution is a.e. absolutely continuous. Characterization of the invariant distribution in the remaining cases is still an open question. The entire analysis is summarized through a bifurcation diagram, drawn in terms of pairs .Received: 9 April 2002, Revised: 29 October 2002, JEL Classification Numbers: C61, O41.Correspondence to: Tapan MitraThis research was partially supported by CNR (Italy) under the "Short-term mobility" program and by M.U.R.S.T.

Voting requirements, concessions, international side payments and the European Monetary Union

This paper addresses the question of criteria for selection of EMU members. We identify two factors in the decision process: (1) The costs and benefits which the individual countries attribute to alternative EMU arrangements (`hard-core', medium-sized, all EU members), and (2) the binding institutional restrictions, i.e., the distribution of votes in the European Council and the minimum vote requirements. Within this framework the EU countries are assigned to different groups according to their degree of convergence. Based on stability concessions and side payments these groups decide on the final EMU composition. We show that minimum vote requirements can lead to a suboptimal size of the EMU and can threaten the feasibility of a multi-speed monetary union.
