我国经济结构动态变动后的下一步 总被引:1,自引:0,他引:1
经济的非平衡增长近年来在宏观经济的研究中广受关注。利用1952~2009年的样本数据,分析检验发现,我国经济具有非平衡增长的基本特征,这导致了我国经济结构的升级演进路径呈现出结构转变性质;在所选择的样本期内,农业对经济增长的拉动作用呈现出倒U型曲线的特征,而服务业对经济的贡献则表现出逐步增加的势头。另外,经验分析的结果表明,我国经济可能正经历长期的结构调整。因此,采取合适的措施使我国经济持续长久增长至关重要。 相似文献

汇率作为宏观经济调节变量,在受到其它经济条件或经济因素影响的同时,其变动对国民经济也有着广泛而复杂的作用。通过对中国汇率制度历史演进的分析,可以发现人民币汇率的变动始终与中国产业结构的调整息息相关。文章以价格这一中间变量作为动力因素,建立价格穿越模型,分析汇率变动引起产业结构调整的传导路径与作用机理。 相似文献

This paper investigates the impact of rating agencies in a market with asymmetric information. In particular, the role of credit rating agencies as an intermediary between investors and bond issuers is discussed. We model this setting in a dynamic framework in which both rating agencies and bond issuers are of heterogeneous quality. Rating agencies can apply costly research technology to reveal the fundamental nature of bond issuers and engage in rating smoothing. We show that rating smoothing can compensate for low research quality, even though it is accompanied by a quality deterioration in the rating market and market clustering. Moreover, low-quality bond issuers have a general tendency to match with low-quality rating agencies. If investors place a strong emphasis on the reputation of rating agencies, rating markets also tend to be strongly clustered. 相似文献

ABSTRACTUsing a cross-regional analysis of China, this article shows that the China model view is factually false and the universal model view is factually true. It is the marketization and development of non-state sectors, rather than the strong power of government and the state sector, that have driven the Chinese economy to grow fast and to be increasingly innovative. If China wants to sustain its economic performance, it must stay on the way to continuing marketization. Otherwise, China will fall into stagnation. 相似文献

We conduct an empirical analysis of the term structure in the volatility risk premium in the fixed income market by constructing long-short combinations of two at-the-money straddles for the four major swaption markets (USD, JPY, EUR and GBP). Our findings are consistent with a concave, upward-sloping maturity structure for all markets, with the largest negative premium for the shortest term maturity. The fact that both delta–vega and delta–gamma neutral straddle combinations earn positive returns that seem uncorrelated suggests that the term structure is affected by both jump risk and volatility risk. The results seem robust for macroeconomic announcements and the specific model choice to estimate the risk exposures for hedging. 相似文献

This paper analyses the effects of dynamic correlations between stock and bond returns issued by the same firm on the speed of adjustment towards target leverage. The results show that the estimated correlations are time varying, show persistence and differ among firms. Analysis of the potential explanatory variables reveals that the correlations decrease with negative expectations about future aggregate risks, but only for firms with a low default probability. In contrast, correlations are positively associated with specific risk measures, especially idiosyncratic stock risk and financial leverage. The positive relationship between the correlations and the leverage ratio suggests that target leverage can be achieved faster when the stock–bond correlation is high. Our results show that this is the case. 相似文献

成本计量模式与企业成本控制机制研究 总被引:3,自引:0,他引:3
成本计量模式存在着制造环节、价值链与商业模式三个视角的划分,它们反映了不同成本效益对称情形,三者间具有层次演进性。从成本与利润的关系看,企业内部就是成本计量,利润则是市场角度的成本补偿计量,企业机制就可以视为在有意义的领域做出独特或某种与众不同的贡献而进行的成本流程安排。企业健康成本结构应该是一个开放的以接纳先进价值观的信息综合体。企业要获得可持续竞争力就必须树立科学的成本控制观念。 相似文献

Since health tourism is one of the most popular and most dynamically developing products of modern tourism, this paper aims at studying the characteristic features of health tourism destinations from a regional and spatial perspective. Accordingly, the authors would like to introduce a new approach of spatial and product analysis of tourism where the market and spatial relations and relevance of health tourism were analysed through the example of Hungary. Although the classic medical tourism centres were established on natural medical water basis, by today, due to product diversification, continuous innovation and the involvement of medical services into health tourism, the geographical embeddedness seems to disappear, thus basically restructuring the market. The methodological novelty of the research is that exceeding the classic supply–demand algorithm, we compiled a complex viewpoint system adequate to the specialities of the given product characteristics. In our study, the authors intend to survey the special characteristics of health tourism focusing on medical destinations through Hungarian examples since the country's leading position in the global market is well recognized, including medical services.

由于当前经济改革中的一些结构性问题使我国居民存在对货币需求的"结构性流动陷阱"."结构性流动陷阱"是我国近年来城乡居民储蓄存款高速增长的根本原因,也是对我国自1997年以来物价变动产生重要影响的一个基本因素.文章首先对当前转型期我国存在的居民货币需求"结构性流动陷阱"形成原因进行分析,其次,依据这个观点对我国近年来出现的通货膨胀和通货紧缩的基本原因和特点进行深入的分析和系统的研究,并就我国未来短期内物价走势进行分析和预测. 相似文献
