循环经济的资金循环障碍及其对策分析

本文基于我国国情分析了循环经济实施的资金循环障碍,提出解决路径,并分析对经济发展的影响。低价甚至无价使用资源环境,不仅导致资源快速耗竭和生态环境恶化,而且客观上阻碍了知识经济的发展。实施刺激循环经济的积极财政政策,不仅对缓和资源消耗过快和环境问题是必要的,而且对促进产业结构调整,扩大就业,增强企业国际竞争力等当前我国经济面临的紧迫问题的解决有积极意义。     

在我国利率市场化改革中金融约束思想的运用

利率市场化是指由资金市场的供求关系来决定利率水平，政府放弃对利率的直接行政干预，作为一项宏观金融制度的变迁，必然会引起社会经济结构的重新整合和不同利益集团的利益重构，在带来巨大收益的同时，也具有极大的社会成本。根据经济人假设，利率市场化能否进行，主要取决于现行利率体制与改革后市场化利率体制之间收益与成本的差额比较。假定R1、C1、R2、C2分别代表现行利率体制与改革后市场化利率体制的收益和成本，则利率市场化能否进行的必要条件是（R2—C2）—（R1—C1）〉0，即利率市场化后的纯收益优于非利率市场化的纯收益。

中国经过20多年改革开放的风雨历程，正在进入竞争日趋激烈的世界大市场，融入国际经济大循环。在现代企业制度相继建立后，要在竞争中取胜，必须彻底转变在计划经济体制下的行政性、经验性、粗放型的管理模式，使之向市场化、知识化、集约化的方向发展，实现经营管理的现代化。随着科学技术不断进步，市场竞争日益激烈，生产经营日趋复杂，企业规模不断扩大，跨地区、跨行业经营的集团公司不断涌现，这就对集团公司的管理提出了较高的要求。本文只探讨集团公司的现金回收管理问题。     

The economic law of population distribution and migration

"The economic law of population distribution and migration has been studied chiefly based on the Chinese situation. The distribution and development of productive forces decide the distribution and migration of population, and in turn, the latter influences the former. The population distributions in three different stages of social development, namely agricultural, industrial and information society, are described. A new concept in population economics is introduced, i.e. population economic density, which is different from the concept of population density. The formula of population economic density is P(population)/R(resources). Many kinds of migration are analysed, and it is believed that the main efficient cause of migration is economy."

Do homeowners achieve more household wealth in the long run?

Despite the public’s faith in homeownership as a vehicle for wealth creation, there are surprisingly few empirical studies of the independent impact of homeownership and its duration on household wealth accumulation. This paper provides the first empirical evidence that homeownership, after controlling for other drivers of wealth accumulation, is positively and significantly associated with wealth accumulation over time. Using the Panel Survey of Income Dynamics, it examines the influence of housing tenure choices between 1989 and 2001 on household net wealth levels in 2001 after controlling for initial wealth in 1989, location, income, education, and other family and personal characteristics that might influence the rate of wealth accumulation. Importantly, the models used also control for the tendency of households to accumulate wealth between 1984 and 1989 (five years prior to the studied period). This approach is used to address the possibility that an unobserved variable—the propensity to save or accumulate wealth—may be associated with both the probability and duration of homeownership and the rate of wealth accumulation. All else equal, those who owned homes and owned for longer periods of time had significantly higher household net wealth by 2001. These results are compelling because house price appreciation over the period was near its long-run average while stock gains were above and real rent increases below their long-run averages. Hence, the findings are suggestive of a positive influence of ownership over long periods on net wealth, even during a period when alternative investments produced higher than normal returns and rents grew slowly. This is especially important because the overwhelmingly majority of households do not sell their homes shortly after buying them. In our sample, those who became owners typically owned for 7 years. Furthermore, most households that bought during a period of declining real home values in the early 1990s continued to own their homes for at least eight years and came out well ahead of those who did not own.
