Due to the lack of pricing mechanisms. companies operating in the government-run industrial park have been receiving free public services, and this has raised many questions. In fact, free services are similar to club goods to firms in the park. The valuation of these services will help reveal how much these services actually worth to the members. This paper first argues that most firms are willing to pay for the public services in the industrial park. Second, their willingness to pay for the continuous services reflects their values. This paper uses the Contingent Valuation Method and estimates the most acceptable payment for public services to be NTS. 4,485 per month. Finally, frequency of the services, the size of the land, and the output value all have positively correlation with the amount of payment for public services.
