Productivity, R&D, and intra-and inter-industry spillovers in Taiwan's aquaculture industry / 研究發展對台灣養殖漁業生產力的貢獻與產業間的外溢效果

碩士 / 國立臺灣海洋大學 / 應用經濟研究所 / 93 / The main objective of this study is to analyze the relationships among productivity, research and development (R&D), intra- and inter-industry spillovers in Taiwan’s aquaculture industry. The externalities of the R&D can result in technology diffusion and economic development. The production values and the governmental R&D budgets on the aquaculture sector from 1974 to 2003 were collected and compiled as the major data of this study.
Five sub-industries -- shrimp, high-prices freshwater fish, low-priced freshwater fish, high-priced shellfish, and low-priced shellfish -- were specified in this study based on the level of prices and species. The production function method was used to estimate the spillover effects among these five sub-industries.The empirical results show that: 1) the R&D inputs over the years made significant contributions on the development of Taiwan’s aquaculture industry except the shrimp sun-industry; 2) variable marginal returns existed in the high-priced freshwater fishes, low-priced freshwater fishes and low-priced shellfishes, and verified the R&D inputs met the demands of above three sub-industries; 3) the shrimp sub-industry enjoyed the highest R&D inputs among five sub-industries and had the least outputs; 4) the direct costs of these five sub-industries had positive impacts on their production value; and 5) labor wage and land rent were significant variables on aquaculture production and equipment input had no impact on production.
