Based on the era background of "Made in China 2025 Strategy" and "High Quality Development", the strategic goals of China's high-tech enterprises face higher development requirements. Therefore, formulation and implementation of strategic competition actions that are compatible with the macroeconomic environment to ensure the rational allocation and effective use of enterprise resources, and truly achieve sustainable and healthy development of these enterprises is of great strategic important. However, the overall development level of China's high-tech enterprises is still witnessed with huge expectation gap especially in the practice of market competition. The competition among Chinese high-tech enterprises around performance is becoming more and fiercer, and the traditional model focusing on single strategic competition means that it could not respond to the volatile or changing market environment. In order to further improve the accuracy of strategic competitive actions, this paper conceptualized that the development of high-tech enterprises requires both correct strategic competitive actions and needs to consider the deep impact of strategic groups. Therefore, this paper intends to provide the perspective of industry structure in the study of the relationship between enterprise strategic competition and enterprise performance. Combined with the research task, this study collected the sample enterprises of telecom industry from 21 Chinese cities to conduct an empirical test using SPSS 23, and draws the following research conclusions: The empirical results found that the enterprises’ quantitative and heterogeneous strategic competitive actions has a positive effect on enterprise performance; the enterprises’ simplicity strategic competitive action has a negative effect on enterprise performance. In general, the attributes of an enterprise’s strategic group in the industry will have an impact on the relationship between its strategic competitive actions and its performance.
