本文构造了一个理论模型,得出了人口流动均衡条件,从而对“民工荒”现象做出了新的解释。本文的结论是迁移成本和就业概率决定了迁移人口的规模;农村工业部门的发展不仅分担城市就业压力,还缩小农民流动规模;农产品价格波动表示的农业剩余波动使得劳动力无限供给神话提前破灭,但并不意味着二元经济的终结。  相似文献

在当代信息社会里,以文化产业为核心的创意产业的发展规模和程度,已经成为衡量一个国家或城市综合竞争力高低的重要标志之一。文化创意产业实践的全球蜂起已成为一个基本的事实和发展趋势。文化创意产业可以建设“文化”广西,“富裕”广西,进而“和谐”广西。利用现代技术提供文化产品,在学校和社区进行“我为广西而骄傲”教育,充分挖掘广西多民族文化,延长现有旅游资源的产业链,面向世界设立“广西旅游文学创作奖”,大力建设广场文化,是发展文化创意产业,打造广西和谐社会的基本途径。  相似文献

高科技社会衍生“人为风险”,西方发达高科技国家倡导新型风险沟通,而后发场域由于系统落差,呈现出迟滞型风险沟通。通过构建全球化高科技风险社会、全球本地化风险沟通的新分析框架,发现高科技社会我国风险沟通面临着风险的社会放大、气泡结构、路径互动阙如、手段叠加、目标战略缺失、过程碎片化等迟滞困境。通过创新理念、吸纳型风险沟通、复合式路径、平衡化手段、连续统、政府学习和政府职能的“七位一体”再造,可有效重塑高科技社会我国风险沟通,推进国家风险治理体系和治理能力现代化。  相似文献

The presentation of corporate disclosure may be explained by impression management. The relative extent of corporate disclosure may be related to information costs. This paper links these two theoretical perspectives by comparing the extent of voluntary disclosure in companies that have chosen to present a dual language approach to reporting, relative to the disclosure provided by companies choosing to report only in one language. The analysis shows that voluntary disclosure is higher in companies that have higher visibility through dual language reporting and whose investors face higher information costs. The analysis also shows that voluntary disclosure by companies reporting only in one language is associated with domestic visibility in market listing and type of industry, while that of companies reporting in two languages is associated with responding to market pressures.  相似文献

Within the context of the Jülich Compatibility Study on Energy Supply Systems the model of the planning cell was used to incorporate participation into the process of policy formulation and evaluation and to gain information about intuitive preferences concerning the four basic energy scenarios constructed by the Enquete Commission of the German Federal Parliament. Planning Cells consist of groups of citizens who are selected by random process and are given paid leave from their workday obligations for a limited period of time to work out solutions for social problems. A total of 24 planning cells were organized throughout Germany to evaluate the four energy scenarios and to formulate recommendations for the policy maker. As a result most citizens favored the more moderate scenarios [1, 5], but were almost equally divided in their preference distribution with respect to the pronuclear (option 2) and non-nuclear scenario (option 3). Using a simplified MAU-model to determine the preferences of each citizen, the surprising result was achieved that more than 40% of the participants reached the highest positive score for the most antinuclear, soft energy scenario. This result could be partly explained by cognitive factors and by preference group influence.  相似文献

This study investigates the structural effect of tourism on alleviating the urban-rural dichotomy and the moderating effect of a dual urban-rural economic structure on Tourism-Led Growth (TLG). A theoretical framework followed by an empirical analysis based on relevant data from 31 Chinese provinces for the years 1998–2013 is presented. The main conclusions of the econometric analysis are that tourism growth can help reduce the urban-rural gap in China, but that the larger the gap between urban and rural economies, the less substantial is the influence of tourism on economic growth in China. Tourism may play an important role in Central-Western and Inland China, but their relatively greater urban-rural economic gap may threaten the positive effect of tourism.  相似文献

Statistical analyses on actual data depict operational risk as an extremely heavy-tailed phenomenon, able to generate losses so extreme as to suggest the use of infinite-mean models. But no loss can actually destroy more than the entire value of a bank or of a company, and this upper bound should be considered when dealing with tail-risk assessment. Introducing what we call the dual distribution, we show how to deal with heavy-tailed phenomena with a remote yet finite upper bound. We provide methods to compute relevant tail quantities such as the Expected Shortfall, which is not available under infinite-mean models, allowing adequate provisioning and capital allocation. This also permits a measurement of fragility. The main difference between our approach and a simple truncation is in the smoothness of the transformation between the original and the dual distribution. Our methodology is useful with apparently infinite-mean phenomena, as in the case of operational risk, but it can be applied in all those situations involving extreme fat tails and bounded support.  相似文献

The dual risk model assumes that the surplus of a company decreases at a constant rate over time, and grows by means of upward jumps which occur at random times with random sizes. In the present work, we study the dual risk renewal model when the waiting times are phase-type distributed. Using the roots of the fundamental and the generalized Lundberg’s equations, we get expressions for the ruin probability and the Laplace transform of the time of ruin for an arbitrary single gain distribution. Then, we address the calculation of expected discounted future dividends particularly when the individual common gains follow a phase-type distribution. We further show that the optimal dividend barrier does not depend on the initial reserve. As far as the roots of the Lundberg equations and the time of ruin are concerned, we address the existing formulae in the corresponding Sparre-Andersen insurance risk model for the first hitting time, and we generalize them to cover also the situations where we have multiple roots. We do that working a new approach and technique, approach we also use for working the dividends, unlike others, it can be also applied for every situation.  相似文献
