This research tried to estimate the operational efficiency of Taiwan semiconductor industry as to study topic, and using industry’’s 85 manufacturers empirical data from 2001 to 2006.The semiconductor industry is Taiwan’’s important industry, although Taiwan held the pivotal status in the global semiconductor industry, in recent years grew the strength to become slow, in addition emerging country mainland China, India fast rose. The Taiwan semiconductor industry must try to catch up the leading country and maintain the competitive power, the semiconductor industry must unceasing promotion, also must promote its operational efficiency and the technical efficiency. By the efficiency measure, can help the manufacturer to understand its competitive advantage and the inferiority, the management and operation shortcoming, with resources use situation. Consequently, this research applies Fried et al. (2002) three stage DEAs to measure the operation performance of Taiwan semiconductor industry , the finding of this research may give correct judgment decision and suggestions to improve the operational efficiency.
The main results are summarized below：
1.The stage one empirical result, the Taiwan semiconductor overall industry with each industrial average efficiency value, every year technical efficiency lower than the scale efficiency, Taiwan semiconductor industry technology inefficiency cause by pure technical efficiency inefficiency, also is the constitution economical inefficiency primary factor.
2.The stage two regression of input slacks on environment variable result; The large manufacturer have the surplus input with the manufacturer induce the resources waste. The manufacturer increases employees production value and employee’’s bonus to issue, will be able to reduce an input item use. The manufacturer increase capital input will be reduce the staff salary, raw material, researches and develops the expense amount of use. Between 2001~2006 years the IC design and the IC manufacture (wafer factory) have the surplus input, wastes the staff salary and R&D input resources situation. Sets up the factory to be long, wastes to the raw material use.
3.The stage three research finds causes of Taiwan semiconductor industry technique inefficiency derive from scale inefficiency，expressed that the manufacturer has not been engaged in the production in the optimal scale of production, another allocation efficiency is higher than technique efficiency, in other word，the prime reason of economic inefficiency is owing to scale inefficiency.
4.Test stage one and three technical efficiency、pure technical efficiency、 allocation efficiency、economic efficiency all has apparent difference, Demonstrated that adjustment of the second stage has the change efficiency value, the environment variable and random error affect the manufacturer efficiency. Therefore, should based on the analysis by the third stage result also only then to have the significance。Provides the manufacturer to make the correct judgment decision-making and the direction of management. |
