The interrelations among environmental performance, environmental disclosure and corporate value, are basic issues of firm environmental behavior. There are different arguments in prior literatures. Based on the investigation of 145 listed chemical firms in China, we obtain results (1) environmental disclosures level is significantly associated with environmental performance; (2) environmental disclosures...
Bass model have been used widely for diffusion curve of a new product in some countries of the world, but only a few studies have explored in the parameters' estimation of bass model. In this paper, Bass model is adopted to fit the diffusion curve of mobile subscribers of China with different parameter-estimation techniques respectively, such as NLS(Non-Linear Least Squares ) ,OLS(Ordinary Least Squares),...
Through researching the domestic and overseas literature, the paper puts forward the components of chain store logistics capability and service quality. It also develops a model to study the influence relationship between chain store logistics capability and logistics service quality. The model is developed based on the current situation and problems in Chinese chain store logistics, which not only...
This paper divided China into three sub-regions to study the corn production. After built yield and acreage model of corn with Nerlove Model, this paper analyzed the factors which affected corn's yield and planting areas in different sub-regions. At the last section, calculated the elasticities of yield and planting area in sub-regions for the short run and the long run. The result indicates that...
This paper pay attention to the hot issue about economic growth mode's change and logistics industry's upgrade in today's society. We begin by describing the practical importance to the transformation and upgrade of China's modern logistics industry, and then survey the literature and accessing to identify four key factors: human resources inventory, market capacity, the manufacturing intensity and...
According to the current status of large and middle-scaled reservoirs in China, the analysis methods of reservoirs downstream flood risk in the event of dam-break and in check flood conditions are established. In the calculation of flooding status caused by reservoir check flood, based on the different characteristics of downstream rivers, water surface profile method, backwater profile method, storage...
The identification of corporation accounting frauds is a major difficulty in financial study. This article establishes an identifying model of financial frauds of Chinese listed firms by adopting Logistic regression analysis. Then it defines public companies whose accounting statements are rejected or denied by register accountant in Shanghai & Shenzhen security market as " corporation with...
This article used VAR model to analyze and verify the symbiosis between Chinese coal mining machinery enterprises and coal mining enterprises from the perspective of static state and dynamic state, it concluded that: there is a co-integration relationship between the actual output value of Chinese coal mining machinery enterprises and the actual value of Chinese coal mining enterprises, namely, there...
Aiming at the insufficiencies of traditional agricultural land grading methods, this study discussed the process and technical route of agricultural land grading based on decision tree analysis method and GIS, constructed an agricultural land grading model based on MATLAB and decision tree C4.5 algorithm. Furthermore, we took Luanwan village of Pingyin county in China for the empirical study, selected...
Evaluation index are long been thought as very accurately reflect stock price by people in China. In this paper, we build theory models to study the relationship between volume, P/B (Price-to-Book value Ratio), P/S (Price-to-Sale Ratio) and P/CF (Price-to-Cash Flow Ratio) and stock market volatility. In current China stock market, individual stock price volatility is a complicated function. The resulting...
Based on the statistical data during the period from 2003 to 2008 released by Henan Statistical Bureau in China, this paper focused on forecasting the amount of the scientists and technicians of Henan province in China, using GM (1, 1) model and regression model. The result of this empirical study is that the grey prediction theory can fit the scientists and technicians amount development precisely...
