In　this　paper,　panel　data　from　Chinese　cities　from　2000　to　2020　were　used,　and　the　intellectual　property　pilot　was　used　as　a　quasi-natural　experiment.　The　double　difference　model　mainly　tests　the　underlying　mechanism　of　the　impact　of　intellectual　property　rights　pilots　on　urban　carbon　emissions.　This　study　revealed　that　IPR　pilots　play　an　important　role　in　reducing　urban　carbon　emissions.　Heterogeneity　experiments　reveal　that　IPR　pilots　are　conducive　to　reducing　carbon　emissions　in　coastal　as　well　as　high　greening　cities　and　that　the　underlying　mechanism　through　which　IPR　pilots　affect　urban　carbon　emissions　mainly　occurs　at　the　level　of　innovation　and　the　optimization　of　the　industrial　structure.　In　addition,　this　paper　also　validates　the　smoothness　of　the　model　by　replacing　the　explanatory　variables　and　performing　a　placebo　test,　which　further　strengthens　the　reliability　of　the　paper’s　conclusions.　Copyright　©　2024　Han.
