| Summary: | 碩士 === 國立中正大學 === 經濟系國際經濟學研究所 === 104 === This paper discusses the performance of selected PCB compare Apple's suppliers and non-suppliers, using Data Envelopment Analysis will get the following points conclusions.
(1) 2010-2015 year 14 PCB manufacturers have the overall efficiency (TE) of the manufacturers only 7 units, 2010-2015 for the remaining 314 firms, showed no efficiency reasons PCB industry from technical efficiency and scale efficiency in terms of both how to increase revenue and gross margin is the primary problem.
(2) The difference between the use of relatively inefficient firms identify gaps analysis of actual and target values, we can see 13 PCB manufacturers mainly invested in project adjustments to fixed assets, display make excessive investment in fixed assets this cost rise caused by PCB manufacturers high and waste.
(3) By the CCR model and BCC mode, the first known non-Apple vendors abundance and Southern Electric can do this 14 vendors referenced most often as a model for the performance of the performance.
(4) Evidence that the sensitivity to CCR model point of view, showing its relative efficiency maximum value of the affected operating expenses, operating expenses for the necessary variables into consideration.
