It could not be used to analyze the complex system with multi-hierarchy correlation factors, the weighted synthetic method for calculating abstract incidence degrees between the system beha-vioral characteristics and correlative factors in different hierarchies is given out,and the hierarchic grey quasi-preferred analysis (HGQPA) model is established. The effectiveness of the HGQPA model is tested by the scientific-technical system of Jiangsu Province. The depth and the range of the application of GQPA are developed, and the HGQPA model is regarded as a new approach to systemically analyze the complex systems with multi-hierarchy correlation factors.展开更多

Our findings are as follows:(1) Without considering exchange rate volatility, capital account openness is subject to a threshold effect, i.e. capital account openness significantly promotes the economic growth of middle-and high-income countries but exerts the opposite effect on low-income countries; and(2) after exchange rate volatility is taken into account, the growth effect of capital account openness is reduced and the greater the exchange rate volatility is, the smaller the marginal effect of capital account openness will be; sample-specific results also proved the existence of the threshold effect. This paper offers the following implications:(1) The effect of capital account openness can be better examined based on risk factors;(2) moderately controlling exchange rate volatility is conducive to acquiring greater benefits from capital account openness; and(3) the threshold effect of capital account openness cannot be overlooked.展开更多

In general, researchers use the traditional gravity model to characterize the contacts that exist between two cities. The traditional gravity model assumes ideal conditions, but these preconditions and their results often do not exist in realistic conditions. Thus, we used a modified gravity model to characterize the city contacts within a specific region. This model considers factors such as intercity complementarities, government intervention, and the diversity of the transportation infrastructure which is characterized as the transportation distance instead of the traditional Euclidean distance. We applied this model to an empirical study of city contact in the Zhujiang(Pearl) River Delta(PRD) of China. The regression results indicated that the modified gravity model could measure city contact more accurately and comprehensively than the traditional gravity model, i.e., it yielded a higher adjusted R2 value(0.379) than the traditional gravity model result(0.259). Our study also suggests that, in addition to urban-regional and metropolitan development, the complementarities of the basic functions of cities at the administrative and market levels, as well as the corporeal and immaterial levels, play very significant roles in the characterization of city contact. Given the complexity of city contact, it will be necessary to consider more relevant influential factors in the modified gravity model to characterize the features of city contact in the future.展开更多

This paper establishes a decomposition model by using the structural decomposition analysis (SDA) method at a regional level. Then this model is employed to empirically analyze the changes of Beijing's energy intensity. The conclusions are as follows: during 2002-2010, except petroleum, the energy intensity decreased and the changes were mostly attributed to the technology changes, while the final use variation actually increased the energy intensity; comparing different periods of 2002-2010, the decline rates of energy intensity for coal and hydropower were decreasing, resulting from the production technology being more energy-intensive than before; the energy intensity changes of petroleum firstly increased substantially and then decreased moderately.展开更多

Our empirical analysis utilized personal interviews, archive documents, and statistical data. Four main processes were discerned： transition from integration to alienation between institutions of higher learning and the larger political and ideological context; a shift from Hebrew University Institute of Communication＇s institutional monopoly to a multiplicity of increasingly competitive communication schools/departments; transition from intellectual hegemony to limited intellectual diversity; and gradually improving status for the communication field among social science disciplines. Our case-study analysis validated the interactive relationship among the model＇s conceptual dimensions, calling for future cross-national comparisons.展开更多

This paper has a research on the textile and garment market, industry cluster and regional economy, recognize textile professional market and regional economy as the main research object, industrial cluster as the intermediary variable. Establish textile and garment market, industrial cluster, regional economy as the main trunk of structural equation model and carry on the empirical analysis. From the empirical analysis, this paper find that the coefficient of textile and garment market effecting on industrial cluster is 0.91, and industrial cluster on regional economy is 0.93, that means results verify hypothesis relationships between the three of them Finally, according to each path coefficients, providing relevant suggestions for the Shanghai area development of textile and garment market, related industries cluster and regional economy development.展开更多

On the basis of the relevant theoretical literature review on the use of empirical analysis methods for the recovery of Pehchaolin brands were analyzed to construct the Pehchaolin brand adjourned intention factors model and validate the model based on the data.

We use Probit model empirically analysis how tinanclal hteracy affect household wealth. The results are as follows： financial literacy does have positive effects on household financial wealth and debt, but do not have significant effect on fixed wealth. Age growth, household income growth, self-owned house and seeking for financial consultant will significantly boost household wealth. Moreover, consumer＇ s self-confidence and risk aversion have positive effects on both fixed and financial assets, but do not have significant effect on debt.展开更多
