| Summary: | 碩士 === 國立中興大學 === 高階經理人碩士在職專班 === 96 === Succeeded by the 3C of information electronics, automotive electronics is the 4th C, this thesis tries to explain the impact of automotive electronics’ R&D activity on corporate performance in terms of input and output perspectives of Cobb-Douglas production function. There are two control groups segmented in sample design, which are index supplier of automotive electronics and supplier of automotive electronics that gets into IT industry, to replace the input of R&D development fee and output for corporate performance with R&D development intensity, to analyze the collected data with Panel Data and explain the connection between input and output to replace variables, and then to further analyze whether there is time lag effect for the impact of R&D development activity on performance and whether it is enlarged or decreased by time increase.
The experimental outcome indicates that Cobb-Douglas can be used to explain the connection among the industry of the automotive electronics and IT electronics, R&D input and output of corporate performance, the operating income will increase when automotive electronics industry R&D input increases, which shows a negative correlation initially, while a positive influence will appear when R&D intensity accumulates to a certain level with time of influence deferred to 2~3 years, the effect will be enlarged by time increase, The increase of IT electronics industry R&D input will have a negative influence on operating income increase, which will be affected by time increase factor, however, the impact of time factor is obviously less than automotive electronics industry. An increase of R&D input of automotive electronics industry has no impact on profitability; the R&D input increase of IT electronics industry that shows a negative impact on the profit of the period. The increase of R&D input of automotive electronics industry has obvious impact on gross income increase and also a time lag effect, IT electronics industry has a negative impact on gross income of the period.
