Based on the dynamic evolution of game and the limited rationality, the question that why the policy for the game of central real estate and a real estate developers was no work was explored. Based on this discovery, it finds that the abolition of unreasonable fees and the introduction of a unified property tax cannot adjust to the price. The only key is to contain the transferring to the consumers, which makes housing prices return to normal levels. Finally, the suggestion that using lower price to release more funds for the expansion of domestic demand and restricting the sources of speculators' funding are gave to government to regulate and control real estate effectively.

Can ERP software bring users economic benefits during a company's operational management? This paper adopts revised value chain method to construct a set of indicators. Using listed companies that implement ERP as samples and the implementation year as the starting point, it compares the value of companies three years before the implementation of ERP and two years after implementation of ERP and testifies it. In order to guarantee the reliability of the conclusion, it uses statistical analysis on the single variable and the multi-variance to test the results. The results show that if the effect of the industry and size factors is left out of account, the IT(Inventory Turnover), FAT(Fixed Asset Turnover), SC (Sales Changes) of companies that implement ERP system are obviously higher than those have not implemented it; the economic benefits of ERP users are better than the non-users; all the economic indicators of ERP users do not show obvious performance change in the implementation year. In the first year of implementing ERP, SC (Sales Changes) and RRE (return on equity ratio) change obviously, showing that ERP brings some economic benefits to users; in the second year of implementing ERP, besides higher SC and FAT than non-users, only ART(Accounts Receivable Turnover) and APT(Accounts Payable Turnover) change obviously, showing ERP brings in changes in users' market and sales segment, but other indicators do not change obviously.

On the international expanding model choice, little attention had been paid to the MNEs from developing countries. Drawing on a sample of 279 overseas subsidiaries invested by Chinese MNEs, the paper examines the factors of influencing the choice between wholly owned subsidiary and joint venture. The binomial logistic regression results show that the host countries' risk, the resource-based industry and the model of establishment have significant positive impact on the preference of joint venture. As a special consideration, the Central Stated-owned Enterprises prefer to choose joint ventures also. Moreover, unlike the MNEs from developed countries, the Chinese MNEs with high R&D intensity are more likely to set up international joint ventures.

The analysis and modeling of high-frequency financial data are new research fields in financial econometrics. The realized covariance matrix, gotten by expanding realized volatility based on univariate high-frequency data to multivariate high-frequency data, can describe volatility and correlation of multivariate time series. The paper gains the realized covariance matrix of the high-frequency data of Shanghai Composite Index and Shenzhen Component Index, and uses VAR model to forecast variance. Then the result is compared with the ones which are gotten by using ARMA model on realized volatility and GARCH model on two indexes. By comparing those three forecast variance by mean squared error, the paper shows that the realized covariance matrix is better than realized variance, and the realized variance is better than GARCH model on variance forecasting.

To develop and validate a clinical prediction rule to identify treatment failure patients with community-acquired pneumonia(CAP) for middle aged and elderly in China, data from the patients aged ≥ 45 yrs with CAP in derivation cohort, internal validation cohort and external validation cohort were analysed by the methods of univariate analysis, multivariate analysis and receiver operating curve. The results showed a prediction rule CCERW based on five independent factors (i.e., confusion; creatinine<60µmol/L; electrolyte disturbances; respiratory failure; WBC>7.5×109/L) which correlated with treatment failure had better predictive capability than PSI, CURB65 and CRB65, and can be used in middle aged and elderly patients with CAP of Han people in China.

With the purpose to enhance efficiency and accurate of emergency dispatch, realize reasonable distribution material quantity, reduce life and property loss caused by paroxysmal emergency events, a dynamic continuous consumption emergency scheduling model is established. Some features of emergency scheduling goals are analyzed. The objective function includes minimizing earliest emergency start time and the least disaster relief participated places. Simultaneously, satisfactory degree of disaster area is also considered in the objective function. Two main categories of constraints, namely, continuous consumption, supply and demand quantity are considered. GA is employed to solve the model, and the basic implement step of GA is given in detail. To employ GA easily, the constraints are disposed with penalty function idea so that they are introduced to the fitness value. To validate the validity of GA, the multi disaster places emergency scheduling problem for dynamic and continuous consumption is abstracted. The experiment shows that by multi running, GA can get multi efficient typical solutions so as to provide significant support for decision-making of emergency scheduling. The global search capacity of GA is strong, and it is suitable to solve complex optimization problems such as emergency scheduling problem under dynamic and continuous consumption condition.

In this paper, an evaluation index system for transportation scientific and technological projects evaluation is built, which composed of three categories and two levels indexes. The weights of indexes are determined by AHP method. Final scores of projects are calculated by grey evaluation method based on reformative triangular whitenization weight function. The evaluation index system and evaluation methods now are an important part of the transport scientific and technical project management platform of Guangdong Transport Department.

Enterprises are in the knowledge based economic environment, and with the rapid growth of knowledge and information they will face a higher level competition on knowledge. The principles were brought forward to define and implement the knowledge value chain model and management. By using the Balanced Scorecard model and Entropy weight, a system was established to evaluate the knowledge value chain management performance in enterprises. Conclusion can be drawn as follows: knowledge value chain of enterprise is customer demand orientated, it is the link structure composed of the processes of knowledge accumulation and innovation, knowledge value chain management performance could be implemented with the reference to balanced scorecard which provides more specific direction and evaluation criteria, and entropy weight method is scientific and effective for the performance evaluation.
