Nearby the main large sewage box culvert project as an example, introduces the engineering design after comparing different place, and scheme, box culvert, profile design, the design of the special structures such as detailed introduction, detailed instructions on the place of innovation and is adjacent to the main channel sewage provides a certain experience in engineering design, at the same time...
This paper investigates the effect of institutional holding on idiosyncratic volatility and information flow. We document that firms with larger pretrade institutional ownership have more access to firm-specific information, which leads to larger idiosyncratic volatility. Institutional trading, with Fund as an exception, has no effect on idiosyncratic volatility and private information. Generally,...
Chinese government has been bothered by the problems for many years that the investments of the government project are always out of control. The examining & approving system is the key of the control process for current government project. In order to avoid making false decision and overcoming the disadvantages of current systems, In the basis of the current problems existed in government-invested...
This paper is intended to research the manufacturerspsila decision-making for R&D investment in defense procurement with incomplete information. On the basis of constructing the model of R&D investment scale adjustment of defense procurement, it explores the equilibrium of manufacturerspsila R&D investment decision-making in defense procurement on condition that the monopolistic contract...
The environment is the key to the success of real estate investment. Therefore, it is very important for the investment environment evaluation of real estate. Firstly, the basic theory of support vector machine for regression (SVR) was introduced, and then a SVM to evaluate the investment environment of real estate was built. Through simulating and comparing with the method of BP neural network, the...
In order to implement the multiple factors and multi-target assessment of real estate investment risk, a model of real estate investment risk evaluation based on fuzzy DEA method was put forward by using the relatively effective evaluation characteristic of Data Envelopment Analysis (DEA). And the feasibility of this method was verified through an example. This study offers a more rational basis for...
As efficient methods of reducing the investment risks, the real estate portfolio optimization methods and models have some defects. The information entropy was used as the risk measuring index, and a self-adaptive ant algorithm with a changing index was proposed to overcome the deficiency of the basic ant algorithm. Then the improved algorithm was introduced into the real estate portfolio. And the...
Prior studies document mixed evidence on the efficacy of independent directors. Different from prior studies, as an important environmental factor, investment opportunity (IO) is adopted to explain the mixed impact of independent directors on earnings conservatism for China listed companies. This paper documents 1 no significant association between earnings conservatism and the percentage of independent...
The study takes 19964 investors from Shanghai, Tianjin and Dalian as samples to prove that there really is home bias with Chinese investors. Under controlling the Urban per disposable income, the paper uses the multinomial logistic model, takes the proportion of holding stock, the cumulative time in the market, age and sex as explanatory variables to detail home basis grade value, and also analyzes...
Based on Prospect Theory, a model about statutory tax rate and capital structure is developed and proves to be proper by regression analysis with data from 307 Chinese listed companies from 2001 to 2005. The results show that there is a significantly positive relation between tax rate and the amount of debt if the firm is in a certain circumstances in which the cognitive bias on the cost of financial...
