Existing clustering algorithms need to specify the number of clusters and to select initial points using human input, which lead to inferior clustering and optimisation outputs. Here, an improved grey decision-making model based on the thought of affinity propagation algorithm and grey correlation analysis is proposed to solve these problems. According to the panel data class and the inter-class candidate...
Under the new historical condition, strengthening the communication and popularization of science and technology is both the requirement to implement the national development strategy and need for social development as well as the basis and key point for the development of popularization of science itself. Relevant data of five characteristic indexes, talents, funds, place, communication and activity...
Based on the literature review, the technology spillover mechanism can be concluded to four categories: demonstration-imitation effect, competition effect, correlation effect and training-flow effect. The technology spillover is always hysteretic. On the basis of multi-period lagged effect of multinational corporations' technology spillover, the paper used panel data and regression method, analyzed...
Regarding the high-tech listed companies, this paper preliminarily discusses the calculation of knowledge storage and regional knowledge level, and analyzes the relations between the knowledge storage and spillover and performance using panel data. The results express: some traditional factors such as growth, operation ability have prominent positive correlation with performance; the asset-liability...
Through empirical study, this paper tests the effect of board size and two-level state toward s corporate performance from over 800 manufacturing listed companies of Japan, and concludes that board size and corporate performance a re significantly positively correlated, one of two staff, board chairman and general manager, in high-growth enterprises is significantly positively correlated with corporate...
This paper groups the panel data of rural commodity circulation and rural economic growth of 31 provinces from 1990 to 2008 into three phases and made quantitative analysis of the impact rural commodity circulation on our country's rural economic growth by bring in variable intercept model. The results show that rural commodity circulation can significantly improve rural economic growth and its influence...
We defined earnings quality as the ability to forecast the future cash flow, stronger forecast capability means higher earnings quality. Choosing all of the A-share in Shanghai and Shenzhen Exchanges between 2001 and 2007, we made a test on the relationship between operating cash flow and accruals. The results demonstrate that the publishing of cash flow can help to increase the financial information...
The difference of performance among Chinese provincial e-governments is very obvious, but the underlying momentums yet to be analyzed in depth. From the intuitive point of view, the e-government development may be affected by a lot of factors such as the local online demand, regional urbanization, regional economic openness, regional economic development level and the other visible or invisible constraints...
On the condition that it is difficult for small and medium enterprises (SMEs) to finance from specialized financial institutions such as banks, trade credit has been an important financing channel for SMEs. On the basis of theoretical research on trade credit, several hypotheses on the influencing factors of SMEs trade credit financing are proposed in this paper. And the panel data of 87 samples of...
In order to improve the accuracy of spatial forecasting based on panel data, the significance of spatial autocorrelation on the panel data is tested by Moran I, the first-order spatial autoregressive model and the Kriging algorithm model are established from the perspective of the cross-sectional data, respectively, and back-propagation neural network model trained by the genetic algorithm is established...
We apply recent panel methodology to investigate the relationship between electricity consumption and real GDP for a set of 12 European Union countries using annual data for the period 1970-2004. Tests for panel unit roots, cointegration in heterogeneous panels and panel causality are employed. The results show a long-run relationship between the series. We estimate this relationship and test for...
In recent years, with the significantly increasing impact of online reviews (a form of word-of-mouth) on consumer purchase decision, clarifying how this kind of information source influences consumer behaviors(usually represented by sales) have been exposed to more attentions in business and academic research fields. Differing from most existing studies which statically analyze relations between online...
