In the process of complex shopping mall development, all the steps (business planning step, pre-sale & completion step, management & operations step) head towards a consistent ultimate goal in an overall business perspective. In this study, we analyze using a structural equation model if an appropriate relations between each of the steps are formed to achieve the ultimate goal. In this study, we find a positive relationship between business planning step and pre-sale & completion step, and also find that for success pre-sale & completion, a faithful business plan is necessary. But we find no statistically significant relationship under significant level 0.05 among business planning step and management & operations step and the level of success, pre-sale & completion step and management & operations step and the level of success, management & operations step and the level of success. This suggests that each of the steps does not form a close relationship to achieve the consistent goal in the complex shopping mall development and each one is doing a short-sighted work for its own profit.

Following principal-agent relationship between government and funding agency effects on efficiency and management of project, this paper suppose that project management cost rate variable on outsourcing and administration of institution, applies multiple regression analysis and logit analysis by using factors that procurement status of institutional operating expenses and each subordinates scale (Budget, subject number) and method (Top-down/Bottom-up), not a total amount, for examining factors following project efficiency analysis and way of commission. The major variables which effect on efficiency of institution are management cost scale (0.36), institutional operating expenses ratio (-0.47), way of outsourcing, the factors that affect way of outsourcing are portion of project management cost (-38.5) and institutional operating expenses rate (-11.7). This means both legal and financial stability are necessary and it is avoidable moral hazard and adverse selection on principal-agent problem.

This study aims to explore how the individual characteristics of the senior job placement project coordinators and the organizational structure in which they work affect their job performance. A survey of 251 coordinators who were working in the senior job placement project agencies were retrieved and used for empirical analysis using the SPSS Win.12 program. The result shows that a sense of self efficacy, the individual traits(understanding of the senior job placement project, attitude towards the elderly) and the organizational structure(the level of formalization of agency) were statistically significant predictors of the level of job performance. The results of this study show that the coordinators who were more confident about themselves, who had more understanding about the senior job placement project, who had more positive attitude towards the social activities of the elderly, and who were working in agencies with higher level of formalization had a higher level of job performance than their counterparts. Therefore, more policy and program considerations should be taken into account in empowering the coordinators, and in providing them with standardized organizational process. This in turn will ultimately enable them to better serve the elderly who participate in the senior job placement projects.

The current PF project is entirely relying on construction company's credibility. As such, it has increased a negative and bad recognition in domestic real estate economy. In addition, PF experts has a perception that a project's safety of future cash flow profitability is more important than the construction company's credibility. So many PF experts make an effort in order to set aside safe project structure of PF and analyse systematically the risks of the project. In common feasibility study of the PF Project, financial specialists and real estate specialists are forecasting and evaluating the suitability of the project through reviewing the development profit from the project of sales. However, cash flow analysis and evaluation from the perspective of mid-sized construction companies are still in the primary level. Therefore, this study has analysed the current feasibility study and go/no go decision making procedures. Then the authors have a new cash flow analysis method from the perspective of mid-sized construction companies, by improving the feasibility study and go/no go decision making procedures.

The megatrend of convergence in finance, telecommunication, and service industries is being spread over the whole industry. It has generated various kinds of contractual alliance or joint venture. Our paper builds a theoretical model for the profit sharing between two firms that participate in a joint venture. The model shows how the profit sharing rule affects the incentives of the participants, and, eventually, the efficiency. We derive the first-best solution of the profit sharing, where no incentive distortion exists. Then, we compare the incentive-affecting cases with the first best outcome, and assess the efficiency and the fairness of distribution. Our analysis shows that if we properly design the decision-making structure on transfer price and production quantity, we can reach the socially optimal efficiency.
