The implementation of innovative provinces as a pivotal pilot measure to promote the in‐depth advancement of ecology in China is a critical undertaking. An accurate assessment of the environmental effects of these innovative provinces is necessary to obtain a comprehensive understanding of the impact of pilot policies and facilitate the promotion of future policies with precision. In this study, the difference‐in‐differences method and the mediation model are employed to analyze the effect and mechanism of the pilot policies for innovative provinces on regional environmental pollution in 30 provinces in China from 2008-2020. The results demonstrate that the innovation provincial policies have resulted in an average reduction of 14.6% in environmental pollution annually in the pilot areas. This conclusion is still valid after robustness tests are eliminated. Furthermore, the mediation effect model provides evidence that the innovation provinces pilot policy reduces environmental pollution through technological innovation and industrial structure upgrading. Additionally, the heterogeneity analysis finds that innovation provinces pilot policy have led to a reduction of 17.4% in environmental pollution in coastal regions and a reduction of 11.7% in inland regions annually. Overall, this research contributes to the existing literature by underscoring the importance of innovation‐driven development for environmental governance and effectively promoting the construction of a resource‐saving and environment‐friendly society.

According to abalone’s growth characteristics, artificial abalone reefs are invented in this paper. The trace elements are added in concrete. The proportion is fixed by test. Ocean alga adheres to reefs with them very well. The craft, matching optimization, curing terms in the island environment and concrete long-term stability in the ocean current are studied to solve the durability of reefs in the marine environment. It shows the durability of fishing reef by high performance, high function, and ecological concrete technology is reliable. Its strength is still increasing for one year and no damage has been found. It is feasible to use the complex admixture, high-quality fly ash, ultrafine silicon powder, surface-soaking-into water-hating material made by our own, adhering-shaking-compact molding equipment made by ourselves and solar-energy-curing technology. Ten thousands of large-scale artificial abalone reefs have been done. A large amount of marine organisms covered the reefs only after 40 days using.
