碩士 === 國立中山大學 === 經濟學研究所 === 101 === This study’s framework is used to bioeconomic of a renewable resource that is used by Gordon-Schaefer models, net revenues to be equal to price times harvest, cost to be equal to cost coefficient times fishing effort being basic analysis. This empirical research utilized mantis shrimp resource statistic data from 1998 to 2008 for conducting the harvest, price, cost, and catch per unit effort by Fishery Bureau. Adding Directorate General of Postal Remittance and Saving Bank announced about one year deposits rates of 2011 1.37% to be discounted rate for the empirical research analysis. The analysis parameters were estimated by Leslie-Delury’s model and Graham’s method including regression analysis, derived resource stock, catch ability coefficient, resource’s intrinsic growth rate, environmental carrying capacity, and importing in maximizing the present value of the net revenue model, substituted real parameter''s value Y, p, c, δ. Solving equilibrium Y, X, E, and comparative statistical analysis of three kinds of fisheries economic models (static, dynamic, and, open access). In the current study, we estimated the status of resources stock of mantis shrimps in 2039 and how external shocks will be occurred in future. Likewise, we predicted the impact of the modification of endogenous variables. Our results may provide a management of fishery resources how to settle a policy in the future. The empirical results were confirmed by model derivation results, then the resources of mantis shrimp in Taiwan hasn’t overfishing condition existed, but the resource of mantis shrimp harvest supply by fisherman that there is the risk of a gradual declined and the collapse of the fishing situation. Caused by many related published literatures about the resource of mantis shrimp in the neighboring mainland China, Japan district that have been overfishing, regulatory authorities should take precautions, in the general management project, such as restraint on harvesting gears, fishing quota, etc. The regulatory authorities need to early prepare for the sustainable management. Furthermore, both of the bioeconomics and economics are important when we reach a decision.
