Introduction Against the backdrop of China’s ambitious “dual carbon” objectives and ongoing economic transformation, this study investigates efficacy solid waste management reform through “Zero-Waste City” pilot program. Methods Utilizing a comprehensive dataset listed companies from regions spanning 2016-2023, we employ sophisticated double machine learning models to empirically evaluate program’s impact on corporate green transformation. Results Our findings demonstrate that policy implementation significantly accelerates transformation trajectory enterprises within designated regions. Through rigorous mechanism analysis, identify three primary channels which operates: enhanced technological innovation, heightened government environmental oversight, increased investor awareness. Heterogeneity analysis reveals differential impacts across ownership structures industry characteristics, with more pronounced effects observed in non-state-owned enterprises, non-heavily polluting industries, traditional (non-high-tech) sectors. Discussion These nuanced provide valuable empirical evidence implications for strategic expansion initiative during 14th Five-Year Plan period, contributing broader literature effectiveness sustainability transitions.

Our study moves beyond conventional constraints that primarily examine patent counts, establishing a novel conceptual framework comprehensively synthesizes dual dimensions—both the volume and caliber of environmental innovations—in aftermath taxation implementation. In contrast to prior scholarship, this investigation extends past mere assessment policy-driven innovation promotion, conducting an in-depth examination how fiscal measures reconfigure architecture elevate excellence. Using comprehensive panel dataset Chinese A-share listed companies from 2012 2022, we employ difference-in-differences methodology with multiple robustness checks establish causal relationships. findings reveal three key insights: First, contrary Porter Hypothesis, EPT implementation shows negative correlation green activities in pollution-intensive sectors, particularly pronounced among private enterprises, smaller firms, highly competitive markets. Second, tax policy demonstrates asymmetric effects across categories, predominantly constraining invention patents while having lesser impact on utility models. Third, aggregate applications decreases, document significant improvement mean quality, especially model patents. The quality-enhancement effect strengthens over time, even as quantity-reducing gradually attenuates. Through detailed mechanism analysis, identify corporate liquidity reduced R&D expenditure primary channels through which affects outcomes. These contribute theoretical discourse regulation by highlighting quality-quantity trade-off responses taxation. results provide important implications for optimizing instruments promote sustainable technological advancement maintaining quality.

Climate change has emphasized the need for sustainable practices across industries, including insurance. This study explores management priorities greenhouse gas (GHG) emissions in insurance sector, focusing on perspectives of marketers and brokers. It aims to identify critical emission sources propose effective strategies carbon reduction. Using analytic hierarchy process (AHP) importance–performance analysis (IPA), this evaluates significance performance GHG sources. Results reveal that both brokers prioritize indirect emissions, especially those from purchased electricity. However, emphasize investment-related impacts, while focus during use phase sold products. Purchased electricity is a well-managed source, products require immediate attention. concludes companies should high-importance underperforming Recommendations include improving energy efficiency electricity, promoting low-carbon product usage, reallocating resources lower priority areas like investments capital goods. By implementing these strategies, can align environmental goals with operational priorities, enhance sustainability practices, reinforce their reputation as socially responsible enterprises.
