| Summary: | 碩士 === 中華大學 === 科技管理學系(所) === 97 === he Taiwan’s government encourages the hi-tech industry in order to push the economy growth. The optoelectronic industry also keeps growing and accelerating that predominates the second amount of capital relevant business currently. Meanwhile, it attracts investors’ attentions and interests in high rates to invest. LED industry is one of the optoelectronic industries, and is positively progressing in Taiwan. Fortunately, the conscious raising of environmental protection, there are many countries have planned to replace incandescent bulbs with LED devices, which are energy-saving and less-polluting. Therefore, the LED industry is more desired by people. Domestic supply chain of LED industry are well-developed, especially the downstream assembly-and-testing houses. In the light of this, the purpose the this thesis is the downstream business performance evaluation for the LED industry.
According to the producing process of LED industry, we can divide this research into two aspects -- the profitability performance and the marketability performance. Profitability represents the profit performance of company management; marketability is about the performance stock market. In order to discuss the influences between those two aspects, the two-stage performance-evaluating model is applied for the evaluation. At the final of this research, we apply Malmquist Index to evaluate overall technique changes of profitability and marketability performances of LED companies. We expect to get more information from the observation, which would be helpful for analyzing the performance of LED manufactures, and creates further strengthen for the research framework.
From the result of research, we can discover the performances of profitability and marketability which have no positive relationship. The LED companies have higher overall performance but have less marketability performance; the most crucial influence is the output from the marketability performance. Hence, we can enforce the overall performance by raising the output from the marketability performance. Investors could care about the LED companies with higher overall performance, higher profitability performance and higher marketability performance, which would have more stable profits than other companies. This research provides lots different ways to analyze the complex industry, assisting LED companies to improve their performances. While, we explaining the relationship between worse performances and producing process for investors which can provide the consideration for investors to determine the accuracy of decision-making.
