中国在现代化进程中面临着一些现代性问题的困扰,其中,贫富分化成为社会矛盾的焦点之一。改革开放以来,中国居民生活水平得到整体提升,但也出现了结构上的分化。造成贫富差距的原因是复杂多重的。其中,城乡二元体制造成了城乡资源分配不公和收入差距,垄断行业的存在则使得资源在少部分群体中集聚,加深了贫富之间的鸿沟。此外,中国的社会保障制度没能充分发挥其调节作用,使得部分底层群体无法解决温饱问题,造成"极贫"群体的出现。值得关注的是,单位体制下的既得利益者,在住房制度改革后又获得福利性住房,住房不公平由此产生财产不公平。国家对于不断拉大的收入差距主要采取宏观政策加以调控,改革财税制度和完善社会保障同时进行,但这并不能因此改变由城乡二元体制和垄断等所带来的必然结果,因而只能起到局部调节收入差距的效果,不能实现真正的社会公正。 相似文献

This paper uses a model of strategic interaction among firms –that set discriminatory and nonlinear prices– in addition to public information on prices of the plans marketed by the three major mobile phone companies, to assess the extent to which on-net/off-net price differentials in the plans they offered could represent predatory practices in the mobile telephony market in Chile. The results show that the largest companies offered a few plans with an off-net/on-net price differential larger than what a competitive theoretical model predicts. This larger differential is consistent with the notion of predation defined by Hoernig (2007) as reducing a competitor's profits. Despite the fact that these plans were a small fraction of all the plans mobile phone firms offered, they were recently banned by the antitrust authority because of their potential anticompetitive effects. 相似文献

In the Ming and Qing Dynasties (1368–1911), China saw rapid development in industrial and commercial sectors. Over this period, a group of merchants originating from the inland province of Shanxi gradually built a multilevel financial system and became leaders in China’s banking sector. The system of financial institutions they established (pawnshops, seal shops, money shops, loan banks, and draft banks) each had a unique business model, with specific target client group and carefully designed risk management. They were also interconnected to allow for flexible capital flows, contributing to the fast economic growth in this period. Nevertheless, the traditional system also had limitations, leading to its replacement by modern banks eventually. 相似文献

Over the past centuries, land systems in Italy experienced fundamental shifts, owing to the availability of new energy forms, population surges, and technological progress. The 20th century was characterized by massive productivity increases, accompanied by gradual land abandonment and the return of forest land. We here analyze 120 years of land system change in Italy, applying the human appropriation of net primary production (HANPP) framework, a metric for socio-economic pressures on terrestrial ecosystems. HANPP allows integrating ecological with societal perspectives, by systematically quantifying (a) biomass harvest and (b) the difference between potential productivity of ecosystems and current productivity induced by land use processes, such as land conversion, or land degradation. Besides assessing national trends we calculated HANPP separately for the Italian North and South between 1934 and 2007, in order to scrutinize if high regional discrepancies in terms of natural and socio-economic preconditions translate into diverging land system trajectories. Our results show that national HANPP has been declining from 78% of natural productivity before WWII to 56% in 2007, indicating a declining land -use induced pressure on biomass flows over time. Simultaneously, biomass harvest increased by around 26% due to agricultural intensification, despite shrinking croplands. Although we found a significant difference between the Northern and Southern region in the absolute levels of several land use indicators related to biomass appropriation, the overarching trends of land system change were remarkably similar in both regions. This suggests that underlying drivers of land system change, such as policies aimed at land-use intensification and structural change were equally dominating land system trajectories in the North and South of Italy, not withstanding their socio-ecological divergences. 相似文献

This paper analyzes the channels through which financial liberalization affects bank risk-taking in an international sample of 4333 banks in 83 countries. Our results indicate that financial liberalization increases bank risk-taking in both developed and developing countries but through different channels. Financial liberalization promotes stronger bank competition that increases risk-taking incentives in developed countries, whereas in developing countries it increases bank risk by expanding opportunities to take risk. Capital requirements help reduce the negative impact of financial liberalization on financial stability in both developed and developing countries. However, official supervision and financial transparency are only effective in developing countries. 相似文献

Fresh produce supply chains have special characteristics, notably, that the quality of the product (fruit or vegetable) deteriorates continuously over time, even under ideal conditions. In this paper, we begin with explicit formulae for fresh produce quality deterioration based on chemistry and temperature and provide a path-based framework. We then focus on farmers' markets, the popularity of which has been growing due to consumers' greater awareness of and interest in product quality and emphasis on health. Farmers' markets, as examples of direct to consumer channels and shorter supply chains, are studied in the framework of game theory in both uncapacitated and capacitated versions. A case study of apples in Massachusetts, under various scenarios, including production disruptions, provides quantitative evidence of the applicability of our supply chain network approach. 相似文献

在中国性别就业差异持续扩大的背景下,文章基于2004-2007年的中国工业企业数据库检验了外资进入是如何通过竞争效应对企业性别就业差异产生影响的。结果显示,外资进入程度越高的地区与行业具有越低的性别就业差异,外资进入程度每增加1%,我国内资企业女性就业份额将会增加0.0407%,且这一结果在考虑了抽样偏倚、不同外资范围的界定、使用不同外资进入程度衡量标准和控制内生性后依然十分稳健。进一步的研究显示,外资进入通过提高企业面临的竞争程度来促使以利润最大化为目标的企业雇佣更多成本较低的女性劳动力,进而降低性别就业差异。更为重要的是,外资进入产生的竞争效应对于性别差异的影响在不同受教育群体之间存在差异,其对受过高等教育,特别是受过研究生以上教育的群体影响最大。文章结论表明,在经济全球化背景下完善市场竞争机制和提高女性受教育程度将有利于减少性别就业差异。此外,文章也为研究外资进入的社会经济影响提供了不一样的思路。 相似文献

Engel's law expresses a “negative stochastic association” of income and the proportion of income that is spent on food. However, there are many quite different notions of “negative stochastic association” and consequently there are different ways of defining Engel's law. We relate these different concepts to Engel's original statistical analysis and show that one must give credit to Engel for the first non-parametric statistical analysis of budget-data. 相似文献
