城市总体规划中的空间区划与管制

探讨了城市总体规划中土地规划和空间管制的编制办法与操作程序,尝试提出空间资源区划和空间利用区划的有关概念,针对不同的空间利用分区和亚区提出了相应的空间管制要求,并把这些理念在大连西部地区总体规划实践中加以运用.同时又基于规划实践的体会,总结了提高空间管制规划的科学性和可操作性的若干认知,旨在为土地与空间管制规划的编制提供参考性思路.     

ON THE INEFFECTIVENESS OF FISCAL POLICY AS AN INSTRUMENT OF MACROECONOMIC POLICY

Spending depends on the quantity of money. If an increase in the budget deficit is financed by sales of government debt to non-banks, the quantity of money is unchanged and public borrowing 'crowds out' private spending. But – if the government finances its deficit (or buybacks of existing debt) from the banks – the quantity of money, and hence spending and national income increase.     

中国货币条件指数构建及与经济增长的实证分析

货币条件指数作为反映一个国家货币政策松紧程度的指标,自1994年由加拿大银行首次提出后,引起了国际社会的普遍关注。本文选取1998年1季度～2011年3季度间共55个季度的实际利率、实际有效汇率、实际信贷规模缺口作为解释变量,选取实际产出与潜在产出之间的缺口作为被解释变量,使用单方程估计法,通过构造总需求曲线,利用最小二乘法计算各解释变量的权重,得出中国的实际货币条件指数。并通过分析对比中国汇率、利率、信贷规模变动与宏观经济增长之间的关系,验证中国实际货币条件指数对实体经济变动的解释能力。     

Growth,deficits and uncertainty: Theoretical aspects and empirical evidence from a panel of 27 countries

We examine the relationship between fiscal deficits and per-capita income growth in a panel of 27 European countries, allowing for perceived risks, in terms of fiscal sustainability, associated with additional government spending. Such risks are proxied by the conditional variability of manufacturing production and stock market returns and by the unconditional variability of two survey-based economic-sentiment indicators. To help clarifying how fiscal variables impact on growth and to provide a point of reference for the interpretation of the empirical results a structural growth model is first identified. We find evidence of an asymmetric relationship, in that fiscal deficits give rise to adverse growth effects if they coincide with high uncertainty regarding the prospects of the economy and no significant negative growth effects in the low-uncertainty case.     

Excess heterogeneity, endogeneity and index restrictions

A discrete or continuous outcome is determined by a structural function in which the effect of some variables of interest is transmitted through a scalar index. Multiple sources of stochastic variation can appear as arguments of the structural function, but not in the index. There may be endogeneity, that is observable and unobservable variables may not be independently distributed. Conditions are provided under which there is local identification of measures of the relative sensitivity of the index to variations in pairs of its possibly endogenous arguments, namely ratios of partial derivatives of the index.     

公平和效率为导向的内部控制信息披露方式的转变

自《萨班斯--奥克斯利法案》颁布以来,美国上市公司内部控制信息披露方式由自愿性披露转变为强制性披露。而在2008年我国五部委联合发布的《企业内部控制基本规范》标志着我国上市公司内部控制信息也开始向强制性披露方式转变。论文试图用经济学的公平与效率理论分析内部控制信息由自愿性披露方式转变为强制性披露方式背后的原因,经过分析发现披露方式的转变是促进资本市场效率向保障资本市场公平的转变。
