对我国高GDP增长率发展模式的一些思考

改革开放以来,我国一直保持着高GDP增长率。本文通过对一些数据的分析和与国外对比,对如此高的GDP增长率背后隐藏的一些问题进行了思考,发现目前我国的GDP构成存在一定的畸形,尤其是消费和固定资产投资;同时高GDP增长率发展模式下,不利于我国发展"生态经济",同时社会公共事业也面临种种问题。同时还分析到目前的国内外形势都已不适合追求如此高的GDP增长率。本文还对解决这些问题提出了一些建议,以促进我国经济持续健康的发展。     

从变迁历史看人民币汇率制度改革新思路

本文介绍了人民币汇率制度的变迁历程,主要包括改革开放前的起步阶段、可调整固定汇率钉住制、钉住货币篮子和改革开放后的汇率双轨制及两种不同的有管理的浮动汇率制度。通过对历史上汇率制度的探讨和我国现状的分析,笔者认为我国汇率制度的改革应沿着"有管理的浮动汇率制—爬行钉住制—浮动汇率制"这条道路稳步发展,随着人民币汇率波动的逐步加大,人民币汇率制度最终过渡到浮动汇率制度。     

Fear of Floating and Pegging: A Simultaneous Choice Model of De Jure and De Facto Exchange Rate Regimes in Developing Countries

We present an analysis of the determinants of de jure and de facto exchange rate regimes based on a panel probit model with simultaneous equations. The model is estimated using simulation-based maximum likelihood methods. The empirical results suggest a triangular structure of the model such that the choice of de facto regimes depends on the choice of de jure regimes but not vice versa. This gives rise to a novel interpretation of regime discrepancies.

Testing the Unstable Middle and Two Corners Hypotheses About Exchange Rate Regimes

The recent rash of international currency crises has generated considerable interest in the role that exchange rate regimes have played in contributing to these crises. Many economists have argued that efforts to operate adjustably pegged exchange rate regimes have been a major contributor to “the unstable middle” hypothesis and some have argued that this unstable middle is so broad that only the two corners of hard fixes or floating rates will be stable in a world of high capital mobility—the two corners or bipolar hypothesis. Two recent empirical studies by researchers at the International Monetary Fund reach opposing conclusions on these issues. We examine the issue further and show that conclusions can be quite sensitive to how exchange rate regimes are grouped into categories and the measures of currency crises that are used. In general we find that the dead center of the adjustable peg is by far the most crisis prone broad type of exchange rate regimes, but that countries need not go all the way to freely floating rates or hard fixes to substantially reduce the risks of currency crises.

Estimating the Equilibrium Effective Exchange Rate for Potential EMU Members

In this study, we attempt to examine the possibility of emergence of significant fluctuations of the exchange rates in the future for the candidate EMU countries. In doing so, we estimate the equilibrium rate of the nominal effective exchange rate for Poland, Hungary, Slovak Republic and Malta through the BEER and PEER approaches. While the PEER-based estimation implies a large misalignment rate for the Hungarian forint, the BEER-based analysis shows that the present exchange rates of the countries considered do not deviate significantly from their equilibrium rates. As a consequence, based on BEER analysis, we do not expect large fluctuations in the effective exchange rates among the currencies considered. Hence, the relevant effective exchange rates are expected to be relatively stable. As a matter of fact, the entry of those countries into EMU is not expected to weaken the stability of Euro.

Exchange Rate Pegs, Fiscal Policy and Credibility

In a fixed exchange rate regime, an exchange rate change can be a swift way to change the real exchange rate in the short run. Fiscal policy also affects relative prices, and fiscal policy response to various types of shocks can therefore be crucial for the credibility of an exchange rate peg. We develop a model within which fiscal policy plays a crucial role for ensuring the viability and thus credibility of an exchange rate peg. We use the insights of this model to take a closer look at Denmark, which has successfully pursued a fixed exchange rate policy since 1982.

稳步推进我国利率市场化改革的思考

目前对进一步放开存款利率管制,在商业银行、央行间接调控机制、金融市场环境等方面还存在一些问题。对稳步推进我国利率市场化改革,本文提出的建议为:分类逐步放开存款利率上限;鼓励金融产品创新,促进存款利率市场化;培育市场基准利率,完善利率传导机制;构建公平的市场竞争环境,加快商业银行业务转型;加强金融监管,建立存款保险制度。     

论中国城镇住房自有率与住房保障的关系

居住是劳动力再生产的基本需要,是一种刚性需求,必须予以满足。购买住房所有权是满足居住需求的一种方式,但不是所有的消费者都有足够的支付能力购买商品化住宅。中国城镇极高的住房自有率完全是中国城镇住房保障滞后的结果,降低中国城镇住房自有率有赖于中国政府扎扎实实推进住房保障工作。由于中国各地情况不同,城镇的住房自有率不宜硬性规定,但各地住房保障水平必须有统一标准。     

基于C-D函数的吉林省建设用地贡献率区域差异研究

随着城镇化的不断发展,建设用地对经济发展瓶颈作用日益凸显,为合理利用土地资源、优化土地利用结构,探讨土地对经济增长贡献率,以吉林省9个地级市(州)为研究对象,利用C-D函数,对其2004-2011年的建设用地贡献率进行测算,并用ArcGIS 10.0进行聚类,探讨其空间差异及原因。结果表明:1建设用地对经济增长的贡献率在14.05%~55.47%,且存在明显的区域差异,其区域差异主要与自然环境、社会经济条件相关;2建设用地投入对经济社会发展有重要支撑作用;3今后要不断优化产业结构,转变经济增长方式,走科技创新型和资本、资源集约型道路。
