摘要

The functions of VTS are to ensure the security of waterways in the port, improve the efficiency of vessel navigation and avoid the pollution of the water, which is an important approach to water traffic management. It has apparent achievements in enhancing port operation efficiency and promoting the development of related industries. As a public service, the investment and operation cost of VTS is high. It has significant indirect economic and social benefits but relatively small direct economic benefits or profits. There is a lack of a unified method for the quantitative assessment of the VTS economic benefits. It is a meaningful topic that should be further explored in theoretical research. This paper analyzes and evaluates the connotation of VTS economic benefits and defines the scope of direct and indirect economic benefits. The direct economic benefits are classified with the specific business of VTS to establish a basic model, and sampling analysis is used to measure them in the application. For indirect economic benefits, the Input-Output Analysis (I-O) is used to measure them. The operational data of the Tianjin VTS is used as an example for verification. The correct understanding and evaluation of direct and indirect economic benefits generated by VTS is an inherent requirement to reflect the operational performance of VTS objectively and provides a scientific decision-making basis for the continuous investment and operation of VTS.
