论强制性环境治理制度的实施效率

In the eco-environmental governance system,the compul-sive institutions are the most important as well as the mostcommonly utilized.A nation utilizes its administrative,lawand economic power to forbid,boost,bestir and help indi-viduals’behavior concerning environmental governance toensure the realization of eco-environment conservation.The fact,however,turns out to be disappointing about theimpulsive institution’s implementation.Actually,the unsatis-factory practices sometimes even lead to“…

FDI对中国国内投资影响的实证分析

在开放条件下,FDI会对东道国国内投资产生强有力的影响,这种影响体现在FDI对东道国国内投资产生挤出效应或者挤入效应。本文对1987—2001年FDI对中国国内投资的影响进行了检验,结果表明:在最近的15年间,FDI对国内投资总体上存在显著的挤入效应;对大多数省份的投资也存在挤入效应,但在东部沿海省份挤出效应和中性效应则占一定的主导地位;FDI对不同地区投资的影响程度也存在明显的差异,呈现出由东向西渐次减弱的状态。

Inter-enterprise arrears in economies in transition

In the context of economies in transition, the paper argues that an excessive liquidity squeeze could throw the economy into a persistent state of low economic activity. In such bad equilibrium, enterprise transactions become largely demonetized, with a chain of arrears, a form of involuntary credit, spreading over the entire system. The empirical analysis of the Romanian experience seems to support the view advanced in the paper.     

The hidden value of air transportation infrastructure

Air transportation is a key strategic asset in that it provides access to markets and thereby enables the economic development of nations. Thus, in order to maintain their competitiveness in a global economy, countries must invest in air transportation infrastructure to ensure their ability to meet current and future demand for aviation services. The objective of this paper is to develop and illustrate a methodology for evaluating the strategic value of air transportation infrastructure, in particular the benefits associated with the ability to react quickly to changes in the market. The hypothesis is that by recognizing and taking advantage of this strategic value, it may be possible to design better policies for aviation infrastructure delivery.The methodology developed here uses system dynamics to model different strategies for infrastructure delivery. These strategies are defined by three variables: the amount of capacity increase, the time to deliver the capacity and the congestion threshold that triggers the need for capacity delivery. Monte Carlo simulation is used to take into account multiple sources of uncertainty. The model shows that a strategy of capacity delivery based on small increments and short response times can yield more benefits than strategies that consider large capacity increases and long response times. Furthermore, in the specific airport example considered here, it was found that a congestion threshold of 75% should be the trigger for capacity enlargements if strategies based on small capacity increments and 1 or 5 years to increase capacity are considered. The lesson for decision-makers is that congestion delays must be addressed with foresight.
