To investigate the latent relation between technology innovation and eco-environmental systems and promote their coordinated development, we integrated the coupling coordination model and panel vector autoregressive model to examine the evidence from China. The research reveals that the technology innovation benefit and eco-environmental governance and endowment are the prominent factors for optimizing the two systems. Moreover, the findings show that the coupling coordination degree of eco-environment and technology innovation in China presents an upward trend. In terms of the dynamic interaction between technology innovation and eco-environment, the influence of the former on the latter is timely while that of the latter on the former is lagging (except for the central region). The weak coupling coordination degree implies that the mutual promotion of technology innovation and eco-environmental systems has not yet formed. The policy implications are proposed accordingly to promote coordinated development of eco-environment and technology innovation in China.
