逐步剥离:我国铁路重组合理组织边界的初步探讨

引入竞争、提高效率是我国铁路重组改革的重要目标指向，因此组织边界的确定以及与之相配套的竞争激励措施已成为重组模式选择的关键议题。本文以自然垄断和交易成本理论为指导，以竞争激励促进企业运行效率为依据，通过对世界各国多种重组模式的垄断与竞争格局进行比较分析，提出了用逐步剥离的方式逼近我国铁路重组合理组织边界的改革思路。     

Capital mobility,wage bargaining,and social insurance policies in an economic union

In a two-country model with mobile capital we analyse decentralized social insurance policies. These policies are a compromise between the preferences of workers and capital owners. Due to wage bargaining, worker-based social insurance contributions are borne by capital owners. These contributions affect the profitability of investment, and consequently the direction and size of capital flows. Countries will take account of these effects in determining social insurance policy. Noncooperative decision making results in tax competition and an underprovision of social insurance. In addition, increasing economic integration, represented by increasing capital mobility, could imply a divergence of social insurance levels in the two countries.     

国内金融市场完全开放对国有商业银行的影响

按照入世协定书中的开放时间表,我国在入世5年后也即2006年底将实行金融业的全面开放。本文认为,我国金融市场完全开放将对国内商业银行带来深远影响:一是在政策层面,经济政策、金融政策、配套政策的进一步开放将使金融业的进入门槛降低,从而带来竞争主体的多元和竞争的更加市场化;二是在市场层面,客户的金融知识的普及和客户的议价能力的提高造成客户对银行需求也在不断提高;三是在竞争层面上,竞争主体、竞争模式和竞争手段的改变将使银行业面临更为复杂的竞争局面。为应对上述影响,国有商业银行应根据自身优势,扬长避短,根据不同情况,综合运用不同战略,以期达到持续发展的目标。     

中资银行迎接外资银行全面竞争的策略研究

随着中国银行业市场不断扩大对外资银行的开放程度,在华外资银行已在市场份额、客户营销、业务经营及人才吸引等方面对中资银行的经营形成挑战。中资银行只有加快改革进程,进一步提升自身的竞争力,才能在2006年底中国银行业全面开放后从容应对外资银行的激烈竞争。本文结合当前中国银行业的改制过程,提出了中资银行的应对策略,即通过与外资银行的业务及股权合作来弥补自身不足,通过调整经营结构实现经营战略的转型,通过完善公司治理培育自身的核心竞争力,通过解决经营中的实际问题提高市场应变力,通过落实“以人为本”的理念切实提升人力资源价值。     

不完全竞争、交易效率和证券风险

本文提出了一种崭新的理论观点———不完全竞争的市场结构是证券风险的一个重要来源,并利用市场数据进行了实证分析。此外,本文还发现不完全竞争的市场结构会通过影响买卖双方的交易策略而降低市场的交易效率。     

模块化:系统结构与竞争优势

从物理模块、处理模块到价值模块，联系媒介、标准和性质趋向抽象领域和独立自由；从大型电脑、个人电脑到互联网模块化，硬件模块之间关系通过软件实现模块化，使模块化结构更加开放。模块系统利益结构由规模经济、局部经济与范围经济的对立转向规模经济、差异经济与网络经济的兼容，超级模块化和数码化是其关键；市场竞争、产权保护和金融选择等模块化利益机制推动了企业经营目标、模块化动力和模块创新模式演变。模块化不但有来自模块设计、模块化设计、“行路图”设计和组织模块化设计等自身竞争优势，也有来自数码化、创新文化、科学商业化和政府政策等环境竞争优势。     

Incentives and Information Exchange in International Taxation

The exchange of taxpayer-specific information between national tax authorities has recently emerged as a key and controversial topic in international tax policy discussions, most notably with the OECD's harmful tax practices project and the EU's savings tax initiative. This paper analyzes the effects of information exchange and withholding taxes, recognizing that countries which agree to exchange information do not forfeit the ability to levy withholding taxes, and also focusing in particular on the effects of innovative revenue-sharing arrangements. Amongst the findings are that: (i) the transfer of withholding tax receipts to the residence country, as planned in the European Union, has no effect on equilibrium tax rates, but acts purely as a lump-sum transfer; (ii) in contrast, allocating some of the revenue from information exchange to the source country—counter to usual practice (though no less so than the EU agreement)—would have adverse strategic effects on total revenue; (iii) nevertheless, any withholding tax regime is Pareto dominated by information exchange combined with appropriate revenue sharing; and, in particular, (iv) sharing of the additional revenues raised from information provided, while efficiency-reducing, could be in the interests of large countries as a means of persuading small countries to provide that information voluntarily.

Spatial Competition and Shopping Externalities: Evidence from the Housing Market

In search markets, greater spatial concentration of sellers increases price competition. At the same time, though, a greater concentration of sellers can create a shopping externality by attracting more buyers to the site. Using housing sales data, we test for spatial competition and shopping externality effects on prices and marketing time. We find that they reflect both competitive and shopping externality effects from surrounding houses, although the relative strength varies with how fresh the house is in the market, the freshness of surrounding houses, and the phase of the market cycle. New listings have the strongest shopping externality effect on neighboring houses that have been on the market for some time. Vacant houses have their strongest competition effects in the declining market and externality effects in the rising market. Fresh houses on the market reap little benefit from shopping externalities in all phases of the market cycle.     

国内金融市场完全开放对国有商业银行的影响

按照入世协定书中的开放时问表，我国在入世5年后也即2006年底将实行金融业的全面开放。本文认为，我国金融市场完全开放将对国内商业银行带来深远影响：一是在政策层面，经济政策、金融政策、配套政策的进一步开放将使金融业的进入门槛降低，从而带来竞争主体的多元和竞争的更加市场化；二是在市场层面，客户的金融知识的普及和客户的议价能力的提高造成客户对银行需求也在不断提高；三是在竞争层面上，竞争主体、竞争模式和竞争手段的改变将使银行业面临更为复杂的竞争局面。为应对上述影响，国有商业银行应根据自身优势，扬长避短，根据不同情况，综合运用不同战略，以期达到持续发展的目标。     

当前我国国内横向税收竞争的实证分析

目前我国理论研究的不足阻碍了对现实生活中各类税收竞争问题的有效治理。为此,着眼于我国国内横向税收竞争的实践,对其进行总结和归类,剖析其背后的体制与制度原因,评价其经济效应,并由此提出促进我国国内横向税收有序发展的政策措施是必要的。
