区域金融中心形成理论与青岛区域金融中心建设的战略选择刍议 总被引:2,自引:0,他引:2
区域金融中心是以经济区域为基础而形成的资金融通和聚散的枢纽,具有一定经济或政治影响力。具有大量和高质量信息的中心城市应该构建区域金融中心。区位优势、经济发展水平、金融活动的广度和水平、地方政策的作用力等是影响区域金融中心建设的主要因素。青岛在区域金融中心建设过程中存在着目标定位和发展思路不能从根本上提升青岛区域金融发展的实力、采取的主要举措针对性不强和个别关键性政策性措施不到位等战略性问题,需要通过调整目标定位和发展思路、有针对性地调整主要举措和补充完善关键性政策措施等对策予以解决。 相似文献

Traditional IO techniques have been used and applied in detail to the case of the Chinese economy with a view to describing and analysing the gradual, albeit radical, transformation of the Chinese industrial fabric since the beginning of the economic reforms. Using a Biproportional Filter, our study has a threefold objective: to measure and analyse structural change that has taken place in the Chinese manufacturing sector since 1985; to highlight those industries that have been most responsible for the change; and to explain the reasons for these changes. 相似文献

This study aims to assess the role played by information technology (IT) in organizational learning (OL) considered as a process of knowledge creation and determined by the interaction of stocks and flows variables. We also examine how IT and OL influence both business performance and the development of the technological distinctive competencies (TDCs), as well as the latter's influence on leading the firm towards better outcomes. These relationships have been tested via an empirical analysis carried out with a sample of 140 industrial companies, applying a structural equation linear model according to the Partial Least Squares (PLS) methodology. Our findings allow us to confirm that IT acts as an enabler of the OL process and influences on the development of TDCs, which allow the achievement of a better business performance. Such competencies are also the result of OL, thus demonstrating the influences of them both on perceived organizational performance. 相似文献

The purpose of this paper is to explain the sources of energy system lock-in. It presents a comparative analysis of the respective contributions of some features of increasing returns to adoption factors, i.e. learning-by-doing, learning-by-searching and returns to scale effects in explaining the technological change dynamics in the energy system. The paper is technically based on a critical analysis of the learning curve approach. Econometric estimation of learning and scale effects inherent to seven energy technologies were performed by the use of several learning curve specifications. These specifications permit to deal with some crucial issues related to the learning curve estimation which are associated with the problem of omitted variable bias, the endogeneity effects and the choice of learning indicators. Results show that dynamic economies from learning effects coupled with static economies from scale effects are responsible for the lock-in phenomena of the energy system. They also show that the magnitude of such effects is correlated with the technology life cycle (maturity). In particular, results point out that, 1) the emerging technologies exhibit low learning rates associated with diseconomies of scale which are argued to be symptomatic of the outset of the deployment of new technologies characterized by diffusion barriers and high level of uncertainty, 2) the evolving technologies present rather high learning rates meaning that they respond quickly to capacity expansion and R&D activities development, 3) conventional mature technologies display low learning rates but increasing returns to scale implying that they are characterized by a limited additional diffusion prospects. 相似文献

This paper considers structural change tests under regression misspecifications. The asymptotic distortions of regression misspecifications on the Sup-Wald statistic are quantified for a class of drifting data generating processes. It is found that there is no asymptotic distortion caused by regression misspecifications when the misspecification term possesses no shifts. 相似文献

Given a pricing kernel we investigate the class of risks that are not priced by this kernel. Risks are random payoffs written
on underlying uncertainties that may themselves either be random variables, processes, events or information filtrations.
A risk is said to be not priced by a kernel if all derivatives on this risk always earn a zero excess return, or equivalently
the derivatives may be priced without a change of measure. We say that such risks are not kernel priced. It is shown that
reliance on direct correlation between the risk and the pricing kernel as an indicator for the kernel pricing of a risk can
be misleading. Examples are given of risks that are uncorrelated with the pricing kernel but are kernel priced. These examples
lead to new definitions for risks that are not kernel priced in correlation terms. Additionally we show that the pricing kernel
itself viewed as a random variable is strongly negatively kernel priced implying in particular that all monotone increasing
functions of the kernel receive a negative risk premium. Moreover the equivalence class of the kernel under increasing monotone
transformations is unique in possessing this property.
