For more than 20 listed telecommunication network companies in Taiwan during 2014, 2015 and 2016, took out “operating costs” and “assets” as input variables to “operating income”.

The CCR model of the data envelopment analysis method is used to determine the technical efficiency, and the BCC model is used together to find the pure technical efficiency, the scale efficiency, and the Malmquist productivity index. Conduct related performance evaluations to understand the differences in the operating performance of communication network operators. Then use the principle of capital asset pricing model to make the best investment portfolio, and select the four units with the highest total scores to obtain the distribution ratio of asset allocation. Situation and compare the return rate of each portfolio with the stock price index and the broader ii market. Observed 15 times in the portfolio, its return rate was higher than that of the communications network industry stock price index for 6 times, and 9 times lower than the total. The return of the investment portfolio was significantly lower than that of the communications network industry stock price index; compared with the broader market Only 9 returns are higher than those of lower returns, and 6 returns are lower. The return on investment portfolio is significantly higher than the broader market. According to the historical index, due to the influence of other factors of the boom, the study found that the single factor model of CAPM cannot fully explain the Taiwan stock market, and the market efficiency needs further discussion..
