Construction Company Competitiveness Research on Informationization Policies

Construction company competitiveness (CCC) is positively influenced by promoting Informatization in the construction field. This paper explores this influencing mechanism to enhance CCC with the empirical method and event study. To begin with, we selected an index of stock returns and three important policy events in the past several years. Then we set up a market model and got excess returns by subtracting the actual rate of return and the expected rate of return in the window period. At last, we performed a single sample mean test on it. It shows that since 2016, only one policy has shown effectiveness, and based on it, CCC suggests a positive trend in the short term. And in terms of different sub-sectors, the competitiveness improved to a different degree. Three conclusions can be concluded. Firstly, the effective implementation of informatization policies can significantly enhance the competitiveness of companies. Second, continuous response to policies is an essential part of increasing competitiveness. At last, with the same policy carrying out, sub-sector industries have a diverse impact on competitiveness.
