Innovation or introduction? Impacts of the low-carbon city pilot policy on the pathways toward green technology progress.

To examine whether the low-carbon city pilot (LCCP) policy influences the green technology innovation (GTI) or embodied technology introduction (ETI), two different pathways to green technology progress, in manufacturing enterprises in China, this study employs a staggered difference-in-difference (DID) model to evaluate the effects of the policy. The findings suggest that the LCCP policy has stimulated an increase in the quantity of GTI and ETI among enterprises, but reduced the quality of innovation. Large, high-carbon-intensity, and state-owned enterprises are more likely to engage in GTI, while small, low-carbon-intensity, and non-state-owned enterprises prefer ETI. The policy is effective in alleviating financing constraints and improving environmental concerns. Both GTI and ETI play a crucial role in economic performance, while the latter also promotes environmental and ESG performance. Accordingly, we recommend establishing a policy-compatible evaluation system, strengthening mandatory and incentive measures, and cultivating a green innovation ecosystem, etc., to improve the performance of the LCCP policy.

Complex network analysis of carbon emission transfers under global value chains.

Accompanied with the increasing complicated global value chain (GVC) networks is the carbon emission transfers among countries. Utilizing the complex network analysis alongside quadratic assignment procedure (QAP), this paper detects the community structure and influencing forces of the emission transfers under GVCs. The results imply that the bipolar structure of the network transformed gradually to tripolar owing largely to the surging of carbon emissions from China. Evidence on the existence of environmental Kuznets curve (EKC) in the emission transfers from high-income countries to low-income countries, and a U-shape relationship transfers in the reverse direction, suggesting that growing carbon emissions from both low- and high-income countries transferred to other high-income countries gradually. Gaps in technology, especially in patent applications, between source and destination countries played an important role therein.
