||In recent years , the Taiwan government adopts the expansion policies to stimulate the consumptions and investments, such as increasing the public construction. However, the supplies of public constructions not only put the heavy fiscal pressure on government, but also rise some problems, such as the supplies of funds don't fit the demands of funds, the benefits of public constructions can't feedback to its selves, the government doesn't make overall plan before constructing, and even the idle constructions.|
To solve these issues , the constructions should internalize external benefits through several ways, such as raising funds by incremental volume, tax increment financing mechanism, private financing initiatives, transit-oriented development, and the cross-sector operating.
In this study, we mainly discuss about the methods of internalizing the external benefits and prove the effect of cross-sector operating by NSYSU alumni house. To simulate the cash flow of NSYSU alumni house in future 50 years, we discover cross-sector operating really make the alumni house be autarky, although the earnings can't afford the funds of construction, it still can operate without adding the school's financial burden.
Therefore , to evaluate an public construction's performance , we should judge not only its service, but also its financial policy. Through the adequate methods, the public construction could internalize the external benefits and increase the quality of service, even reduce the burden of government and the crowds.
