| Summary: | 博士 === 國立臺灣大學 === 漁業科學研究所 === 91 === The technical inefficiency model, comparative advantage analysis and the approach of optimal production of industry have been chosen to assess the development of the Taiwanese eel aquaculture industry. Our research findings suggest that the average technical efficiency has reached 0.91 for the industry, which implies that a long term effects from researchers and aqua-farmers have made the industry stepping into a mature operation stage.
The indices of net private profitability, domestic resource cost, and net social profitability are calculated for the Taiwanese, Japanese and Chinese eel aquaculture industries. The results show that the comparative advantage of the Taiwanese eel aquaculture industry is higher than the Japanese but inferior to the Chinese.
An econometric model has been adopted in this research to investigate the optimal production of the industry when taking into account the production externality. Our research findings suggest that the optimal production of the Taiwanese eel aquaculture industry ranges from 23,000 metric tons to 26,000 metric tons, after considering the external cost of underground water use and the water pollution. According to the historical record of the Taiwanese eel export to Japan, the Taiwanese eel aquaculture industry can still retain its comparative advantage even after considering the production externality.
Set forth on the simulated results, some suggestions related to future regulation and management are provided to achieve the goals of elevating the competitiveness and retaining the sustainable development of the Taiwanese eel aquaculture industry.
