Innovation is critical for organizations seeking to build and maintain a sustainable advantage in the competitive market. This study aims to construct a moderated mediation model to examine the effects of incremental and radical innovations on competitive advantage, which considers the mediating role of innovation speed and the moderating role of a supportive culture. Data from 201 Chinese firms were collected through questionnaires and the research hypotheses were tested using multiple regression analysis and bootstrapping techniques. The empirical results show that incremental and radical innovations have a significant positive effect on competitive advantage. Radical innovation has a greater impact on competitive advantage compared to incremental innovation. Innovation speed mediates the relationship between incremental and radical innovations and competitive advantage. Supportive culture positively moderates the relationship between incremental and radical innovations and innovation speed. Moreover, supportive culture positively moderates the conditional indirect effect of incremental and radical innovation on competitive advantage through innovation speed. Theoretical and practical implications are further discussed.

Enterprises are the most important core organizations of the country and modern society, and their growth has always been a focal point in the theoretical field. This paper aims to focus on the sustainable development of platform enterprises by exploring the mechanism of platform growth. Thus, this paper reviews the literature and analyzes the challenges faced by platform enterprises during the four stages of birth, expansion, leadership, and self-renewal, as well as the strategies they have adopted. The main aims of this paper are to help understand the growth process of platform enterprises and identify three key points that need to be addressed for sustainable growth, including the disadvantages of resource externalities, the importance of the restructuration of business models, and the urgency of fulfilling social responsibility. To address the exogenous nature of resources, platform enterprises should pay attention to the initiative of complementors, the distribution of benefits, and ecological orchestration. The impact of technology, especially artificial intelligence, on business models and the application of technology to restructure business models should be given attention. It is also necessary to pay attention to how platform enterprises undertake their social responsibilities. A synthesis framework with seven propositions for future research has been proposed.
