借鉴已有相关研究成果,将劳动力转移、农业技术水平与城乡居民收入差距联系起来思考,可以具体地考察劳动力转移对城乡居民收入差距的影响.文章以农业技术水平作为门槛变量,选取2009—2019年中国31个省份的面板数据,利用泰尔指数测定城乡收入差距,以劳动力转移作为核心解释变量构建面板门槛模型,实证得出劳动力转移对城乡居民收入差距的非线性影响.研究发现:劳动力转移可以缩小城乡居民收入差距,且该影响具有单一门槛效应.在农业技术水平较低时,劳动力转移对城乡居民收入差距收敛效应较小;当农业技术水平越过门槛值达到较高水平后,劳动力转移对缩小城乡居民收入差距的效果几乎增加了一倍.此后,通过替换解释变量泰尔指数为城乡人均可支配收入比、替换核心解释变量农业技术水平为农业生产效率重新建立面板门槛模型,发现上述结论仍然成立,其检验结果具有较强的稳健性.文章将农业技术进步、劳动力转移、城乡居民收入差距这三个重要变量纳入同一模型框架中,在加深劳动力流动影响城乡居民收入差距这一视角的研究的同时,对缩小城乡居民收入差距政策的制定提供了重要的参考意义. 相似文献

This study demonstrates the analytical leverage gained from considering the entire college pipeline—including the application, admission and graduation stages—in examining the economic position of various groups upon labor market entry. The findings, based on data from three elite universities in Israel, reveal that the process that shapes economic inequality between different ethnic and immigrant groups is not necessarily cumulative. Field of study stratification does not expand systematically from stage to stage and the position of groups on the field of study hierarchy at each stage is not entirely explained by academic preparation. Differential selection and attrition processes, as well as ambition and aspirations, also shape the position of ethnic groups in the earnings hierarchy and generate a non-cumulative pattern. These findings suggest that a cross-sectional assessment of field of study inequality at the graduation stage can generate misleading conclusions about group-based economic inequality among workers with a bachelor’s degree. 相似文献

陕北方言的疑问句和普通话的疑问句不同 ,只有是非问句、特指问句和选择问句三种 ,且结构格式也不一样。是非问句通常用类似于正反问的“体标记 否定词”格式表示 ;选择问句是在选择项之间嵌入“是”字 ,并于选项末缀体标记 ;特指问句则表现为一系列不同于普通话的特殊疑问代词的使用。同时三种问句格式在语义、语用方面也和普通话的相应形式有一些差别 相似文献

利率变动下的存续期缺口管理和流量比例调整 总被引:5,自引:0,他引:5

在金融自由化和利率市场化的浪潮下,商业银行所面临的利率风险防范问题日益突出。利率风险管理成为商业银行经营管理中极其重要的环节。马考勒存续期缺口管理是现代西方商业银行的主要风险管理手段之一,合理构造存续期缺口可使商业银行净值不受市场利率影响,而流量比例调整可以克服存续期缺口受制于利率变动的不足,综合利用存续期缺口管理对我国商业银行建立风险管理机制起着重要的作用。 相似文献

安乐死历来是个敏感的话题,有关安乐死的争论除在哲学、伦理学、医学等领域展开外,法学界对安乐死从不同的角度发表了不同的观点。近期对这一问题的讨论尤其引人注目,笔者想就此进行分析并进而提出一些自己的看法。 相似文献

目前,我国居民收入分配差距总体上呈扩大态势。但是,因收入分配差距扩大而导致的贫富差别并不等于两极分化,两者既有区别又有联系。因此,我们必须充分重视收入差距扩大造成的负面影响,并采取措施加以解决。当务之急是要对收入过高和过低的两头进行必要的调控,重点是解决贫困问题,将低收入层的收入水平升上去。同时利用国家的财税手段和法律手段,调控收入分配差距。 相似文献

对审委会制度的改革,有人主张废除审委会制度为其核心内容;也有人主张目前应在保留的基础上予以改革和完善。废改之争,焦点是研究方法之争。主废和主改各有其弊,应通过立法程序按照“不审不判”的思路重塑审委会制度,明确审委会审判组织的地位,赋予其合议、陪审、咨询、调研四大职能及案件实体决定权和指导权,并建立和完善相应的程序。 相似文献

Making ends meet: perceptions of poverty in Sweden 总被引:1,自引:0,他引:1
B. Halleröd 《International Journal of Social Welfare》1995,4(3):174-189
During the era after the Second World War, Sweden has built a welfare system based on labor market participation and income maintenance. Low unemployment and decent wages are supposed to guarantee people a labor market income or income maintenance, which in turn should provide a proper standard for everyone. However, a rapid increase in unemployment and economic problems have made the future of the Swedish welfare state more uncertain than ever. These circumstances have, among other things, led to the suggestion that Sweden should abandon the income maintenance policy and create a social policy system with the more limited ambition of guaranteeing everyone a minimum income. In that case, one central question must be answered: what constitutes a decent minimum income in today's Sweden? Where should we draw the poverty line under which people will not be forced to live? These questions are central in the current debate. The consensual poverty line method is used in this article to derive a poverty line relevant for today's Sweden. The results shows that more than every fifth household has an income below the consensual poverty line. That is, they have an income that most Swedes would argue is too low to make ends meet. The level of the consensual poverty line was compared with the National Board of Health and Welfare's guidelines for social assistance. The consensual poverty line was shown to be more generous to small households and the norm for social assistance was more generous to larger households. Finally, the expenditure for guaranteeing all Swedish household a minimum income equal to the consensual poverty line was estimated: more than SEK 25 billion per year. The results in the article casts serious doubt on the ability of the Swedish welfare state to secure a decent income to all citizens. 相似文献

Abstract. A Markov property associates a set of conditional independencies to a graph. Two alternative Markov properties are available for chain graphs (CGs), the Lauritzen–Wermuth–Frydenberg (LWF) and the Andersson–Madigan– Perlman (AMP) Markov properties, which are different in general but coincide for the subclass of CGs with no flags . Markov equivalence induces a partition of the class of CGs into equivalence classes and every equivalence class contains a, possibly empty, subclass of CGs with no flags itself containing a, possibly empty, subclass of directed acyclic graphs (DAGs). LWF-Markov equivalence classes of CGs can be naturally characterized by means of the so-called largest CGs , whereas a graphical characterization of equivalence classes of DAGs is provided by the essential graphs . In this paper, we show the existence of largest CGs with no flags that provide a natural characterization of equivalence classes of CGs of this kind, with respect to both the LWF- and the AMP-Markov properties. We propose a procedure for the construction of the largest CGs, the largest CGs with no flags and the essential graphs, thereby providing a unified approach to the problem. As by-products we obtain a characterization of graphs that are largest CGs with no flags and an alternative characterization of graphs which are largest CGs. Furthermore, a known characterization of the essential graphs is shown to be a special case of our more general framework. The three graphical characterizations have a common structure: they use two versions of a locally verifiable graphical rule. Moreover, in case of DAGs, an immediate comparison of three characterizing graphs is possible. 相似文献
