我国外资利用的经济增长效应——基于内生经济增长模型的分析

The flowing of foreign capital is related with the economic security of one countries. The experiencesand lessons of many developing countries show that the impact of the foreign capital to the domesticeconomic is often the most important factors of the financial crisis. So it is important to a analysis theforeign capital economic growth effect. Based on the endogenous economic growth model, this paper firstdistricts the three cases of the foreign capital impact and give the three factors of the foreign capitalaffecting to the economic path. The using the sample data of China, we analyze the three factors. Theresults show that all the three factor effets are all positive, which means that the foreign capital utility ofChina is efficiency.

FDI技术外溢的动态测算及原因解释

A dyanmic model of measuring technology spillover effects from FDI has been established in thispaper by introducing the adaptive expectation process into the original Feder model, and China' seconomic data are used to calculate the time-series of technology spillovers for China' s FDI. A furtherstudy demonstrates that the interaction of human capital and FDI well explains the changes of spillovereffects, while the degree of openness and the improvement of infrastructure also have a positive impact ontechnology spillover. However, it's hard to make certain the relationship between the technology gap,competitive intensity of domestic market and technology spillovers.     

东西部地区财政支出的实证分析

This article analysed the scale, structure and effects of finance expenditure in western and easternregions of China from 1996 to 2000. The conclusion indicates that both ablolute scale and relative scale offinance expenditure in the two regions have increased. The western regions put the emphasis of financeexpenditure on infrastructure while the eastern regions on science and technology. Compared with easternregions, the problem of finance expenditure in western regions lies in the government expenditure washigher than normal level; the gap in science and education expenditure of every person between westernand eastern regions have been increasing. How to increase the effects of finance expenditure is the mainproblem which western and eastern regions must face, and this problem means more improtance to westernregions.

基于期权方法的动态租赁决策

Many researches concentrated on the analysis of leasing decisions, which afford no flexibility to adjust the term of the leasing during its life. Since these analyses are based on Discounted Cash Flow, it is inadequate for valuing the various options written into many leasing contracts. In this paper, a leasing decision with several real options was analyzed. An option-based numerical analysis is used here with an exampite to value such. discrete-time type of real options.

Air Pollution Materials Damage: Economics and the Law

Recent concerns about the adverse effects of acid rain have increased the attention given to materials damage effects from air pollution. This article surveys the economics of valuing materials damage effects and relates these methods to the technical aspects of estimating actual damages. The current statutory and regulatory framework within which materials damage effects are considered is also reviewed. The key weaknesses of the relevant sections of the Clean Air Act, in terms of effectively using economic and technical information on materials damage, are identified. The article concludes with several general observations concerning the regulation of materials damage effects.     

Spatial prediction of crystalline defects observed in molecular dynamic simulations of plastic damage

Molecular dynamic computer simulation is an essential tool in materials science to study atomic properties of materials in extreme environments and guide development of new materials. We propose a statistical analysis to emulate simulation output with the ultimate goal of efficiently approximating the computationally intensive simulation. We compare several spatial regression approaches including conditional autoregression (CAR), discrete wavelets transform (DWT), and principle components analysis (PCA). The methods are applied to simulation of copper atoms with twin wall and dislocation loop defects, under varying tilt tension angles. We find that CAR and DWT yield accurate results but fail to capture extreme defects, yet PCA better captures defect structure.     

Forecasting Materials Damage from Air Pollution

Forecasts of materials damage from air pollution require (a) knowledge of a “damage function,” (b) an estimate of the exposure of materials to pollutants and other factors that enter into the dose relationship, and (c) the quantity and characteristics of the exposed materials. Uncertainty about any of these factors can lead to unacceptable uncertainty or bias in damage forecasts. Particular attention is given to the influence of the spatial units used to derive forecasts of materials damage. Environmental corrosion can vary significantly over relatively small geographic areas; accordingly, the choice of spatial unit can have an impact on forecasts of damage. The environmental factors that influence materials damage may not be independent over the time of exposure. There appears to be some evidence, for example, that SO₂ is not independent of time of wetness, both factors in metal corrosion.     

An efficient experiment to study superconducting ceramics

Materials formulation and processing research are important industrial processes and most materials know-how comes from physical experiments. Our impression, based on discussions with materials scientists, is that statistically planned experiments are infrequently used in materials research. This scientific and engineering area provides an excellent opportunity for both using the available techniques of statistically planned experiments, including mixture experiments, and identifying opportunities for collaborative research leading to further advances in statistical methods for scientists and engineers. This paper describes an application of SchefK's (1958) simplex approach for mixture experiments to formulation of high-temperature superconducting compounds. This example has given us better appreciation of the needs of materials scientists and has provided us opportunities for further collaborative research.

Materials Damage by Environmental Pollutants: Data Requirements

Damage to materials of construction by atmospheric pollutants falls into three categories: corrosion, soiling, and cleaning damage. All three occur in varying degrees in the absence of pollution; to assess the impact of pollutants on materials of construction, therefore, it is necessary to determine the incremental impact attributable to the pollutants. Research to date has tended to the collection of data on effects of inadequately characterized pollutant complexes on inadequately characterized materials, followed by the imposition of arbitrary regression lines on the data, ignoring the underlying chemical kinetics. An outlook on the problem is given and approaches are suggested that will decompose the series of steps into manageable portions. This viewpoint should lead to increased understanding of the phenomena involved and thus to the ability to set rational thresholds of impact as an ingredient in the process of considering the possibility of basing ambient environmental standards on such data.     

Estimation of Fibre Length Distributions from Fibre Endpoints

Estimating the fibre length distribution in composite materials is of practical relevance in materials science. We propose an estimator for the fibre length distribution using the point process of fibre endpoints as input. Assuming that this point process is a realization of a Neyman–Scott process, we use results for the reduced second moment measure to derive a consistent and unbiased estimator for the fibre length distribution. We introduce various versions of the estimator taking anisotropy or errors in the observation into account. The estimator is evaluated using a heuristic for its mean squared error as well as a simulation study. Finally, the estimator is applied to the fibre endpoint process extracted from a tomographic image of a glass fibre composite.     

Estimation of geodesic tortuosity and constrictivity in stationary random closed sets

We investigate the problem of estimating geodesic tortuosity and constrictivity as two structural characteristics of stationary random closed sets. They are of central importance for the analysis of effective transport properties in porous or composite materials. Loosely speaking, geodesic tortuosity measures the windedness of paths, whereas the notion of constrictivity captures the appearance of bottlenecks resulting from narrow passages within a given materials phase. We first provide mathematically precise definitions of these quantities and introduce appropriate estimators. Then, we show strong consistency of these estimators for unboundedly growing sampling windows. In order to apply our estimators to real data sets, the extent of edge effects needs to be controlled. This is illustrated using a model for a multiphase material that is incorporated in solid oxide fuel cells.
