Does the dual circulation coupling synergy facilitate firm survival?--Evidence from China

The "dual circulation" development pattern is a major economic strategy proposed by China. Using samples gathered from firms located in the Haidian Science and Technology Park in Zhongguancun between 2013 and 2019, this paper constructs an index system for measuring the degree of synergy of the dual circulation coupling of the firms, and then uses the Cloglog survival model to empirically verify its effect on the survival of firms. It is found that the dual circulation coupling synergy of firms significantly contributes to firm survival, a finding that still holds after robustness tests. Mechanism tests show that firm dual circulation coupling synergies contribute to firm survival by promoting firm innovation, market demand, and resource allocation efficiency. Further analysis reveals that the coupled synergy of the dual circulation of firms contributes more significantly to the survival of growing and mature firms, MSMEs, private firms and non-start-up firms. This paper is the first to measure dual circulation. It provides micro-theoretical mechanisms and relevant empirical evidence for the dual circulation coupling synergy for firm survival.
