FDI对合肥市经济增长影响实证分析中期报告摘要：本文基于2000-2019年合肥市及其11个区县的年度数据，采用面板数据分析方法，实证研究了外商直接投资（FDI）对合肥市经济增长的影响。结果表明，FDI对合肥市经济增长呈显著正向影响，且影响具有时间滞后性和区域差异性。具体而言，FDI进入当前一年的1-3年后对经济增长具有显著正向影响，而该影响在不同区域之间存在差异，高新技术开发区和经济技术开发区的影响最为显著。此外，研究还发现，投资规模、开放程度、技术含量等因素也对FDI的经济增长效应产生了显著影响。关键词：FDI；对合肥市；经济增长；面板数据Abstract:BasedontheannualdataofHefeicityandits11districtsfrom2000to2019,thispaperusespaneldataanalysismethodtoempiricallystudytheimpactofforeigndirectinvestment(FDI)ontheeconomicgrowthofHefeicity.TheresultsshowthatFDIhasasignificantpositiveeffectontheeconomicgrowthofHefeicity,andtheimpacthastimelagandregionaldifferences.Specifically,FDIhasasignificantpositiveeffectoneconomicgrowth1-3yearsafterenteringthecurrentyear,andthiseffectvariesamongdifferentregions,withthehigh-techdevelopmentzoneandeconomicandtechnologicaldevelopmentzonehavingthemostsignificantimpact.Inaddition,thestudyalsofoundthatinvestmentscale,openness,technologycontentandotherfactorshaveasignificantimpactontheeconomicgrowtheffectofFDI.Keywords:FDI;Hefeicity;economicgrowth;paneldata.
