环境“二维化”视角下的居民幸福感量化研究：来自中国CGSS数据的新证据

幸福不仅是影响人们行为的重要因素,更是人们生活追求的最终目标。本文基于中国综合社会调查（CGSS）数据,创新性地从环境“二维化”这一研究视角,将环境因素划分为两个维度,即客观存在的环境污染因素与居民主观的环境行为,采用优化的两阶段有序Probit回归模型,沿着“客观存在的环境污染因素——居民幸福感”和“居民幸福感——居民主观的环境行为”两条研究思路展开实证分析,在实证过程中引入控制变量及工具变量,同时对经济因素及地区因素可能导致的组群差异进行考量和比较。结果显示,无论是环境污染对居民幸福感,还是居民幸福感对居民环境行为,其影响均是显著的,且具有异质性;环境污染通过影响居民的身体健康、生活质量和社会活动对居民幸福感产生影响,而居民环境行为则因个体收入和居民幸福感程度的不同产生差异。本文对环境与居民幸福感之间的作用机制展开深入分析,为政府出台环境政策的制定、提升居民幸福感及居民环境行为贡献度奠定理论基础。     

Social protection systems and the future of work: Ensuring social security for digital platform workers

Digitalization is transforming societies and economies worldwide at an unprecedented scale and pace. In the wake of automation and digitalization, new forms of employment have been emerging in various occupations and sectors, such as the digital platform economy. The emergence of new forms of employment, such as work on digital platforms, requires that existing social protection systems adapt to the specific situation and needs of such workers, as to realize the human right to social security for all. Current social protection coverage for workers on digital crowdwork platforms reveals significant gaps in social security coverage. Where such coverage exists, it is often provided through the workers’ previous or additional jobs, or indirectly through their spouses or other family members. This raises questions about digital platforms free riding on the traditional economy with regard to the financing of social security. How can social protection systems adapt to changing forms of work to ensure full and effective coverage for workers in all forms of employment, including those in “new” forms of employment? How can workers in all types of employment, including those on digital platforms, be protected in an adequate and comprehensive way, combining contributory and non‐contributory mechanisms and based on equitable and sustainable financing mechanisms, so as to ensure adequate social protection to all?     

中国劳动收入份额的时空分异特征及动态演变研究

准确描述劳动收入份额的时空分异特征及动态演变轨迹,是破解收入分配领域发展不平衡、不充分问题,进而实现共享发展的一项基础性研究工作。基于1997—2017年中国内地31个省份的面板数据,运用Dagum基尼系数、Kernel密度估计与空间计量经济学相结合的分析方法,考察劳动收入份额的时空分异特征及动态演变规律。结果表明,中国劳动收入份额具有明显的时序波动性和空间非均衡特征,劳动收入份额在地区间具有层次性差距。具体而言,尽管劳动收入份额的空间非均衡程度呈现出不断降低的态势,但劳动收入份额的地区间差异明显大于地区内差异,地区间差异是劳动收入份额空间非均衡的主要动因。劳动收入份额的演变不仅具有时间上的前后连贯性,还具有地区之间的空间关联性。基于二元邻近矩阵和地理距离矩阵的空间收敛性检验表明,中、西部地区内部的劳动收入份额存在明显的“俱乐部”收敛现象。因此,建议积极发展区域间的互补型合作关系,逐渐平滑资源要素分布和经济发展条件的区域差异性,促进各地区的劳动收入份额在差异中提升,在发展中提升。     

“三张”父名问题新解

“三张二陆两潘一左” ,此为西晋“文章中兴”时期的一个重要作家群体。张载、张协、张亢 ,此即“三张”。然其父之名 ,史传有“张牧”、“张收”之异说。其实 ,不少文献可以显示 ,“三张”之父乃张牧。确证此说 ,有助于了解张载之生平仕历 ,有助于读解张载、张协之文学创作     

La signature œnologique: frontières et transferts de réputation chez les consultants vitivinicoles

The category of consultants provides a convenient way to describe how work is organized in the Bordeaux wines classified as grands crus and, also, to study theoretical questions such as the relation between individual and organizational reputations or the incorporation of symbolic assets. Following a presentation of consultancy in the wine industry, questions arise about how the “oenological signature” enters into the operation of the labor market for consultants. This signature, while it is a source of reputation that can be transferred to producer organizations, is an asset that consultants have difficulty assuming because of the importance of the soil and vintage in the making of reputations in the wine industry.

Goodness‐of‐fit tests for the hyperbolic distribution

The authors give tests of fit for the hyperbolic distribution, based on the Cramér‐von Mises statistic W². They consider the general case with four parameters unknown, and some specific cases where one or two parameters are fixed. They give two examples using stock price data.     

人本价值思维方式与科学发展观

“以人为本”是科学发展观最核心的价值取向。要将科学发展观真正落到实处,必须确立“人本”的价值思维方式。“自然界是人的无机身体”,“人是类存在物”,人与自然的和谐、人与人的和谐等,是“人本”价值思维方式的最重要的双向逻辑展开。确立“人民群众是历史的创造者”的理论观念,加强人文精神的培养和淬炼,坚持“人天一体”的生态思想,形成“生人自生”的“类”生存意识,是“人本”价值思维方式形成的重要要素。
