摘要“一带一路”战略是国家主席习近平在2013年9月10日在出席哈萨克斯坦和印度尼西亚时，先后提出了共建“新丝绸之路经济带”和“21世纪海上丝绸之路”的伟大倡议。陕西省作为“一带一路”不可或缺的省份，更应抓住机遇，着重提高公共基础设施的投资效率，为本省的投资额的评估以及调整起到关键性作用。本文运用2007年-2017年的公共基础设施有关方面的数据，采用数据包络分析法（DEA）构建陕西省公共基础设施投入产出效率评价指标，并采用对比分析法得出在“一带一路”背景下，陕西省公共基础设施在战略提出的前后的投资差异，以及对投资效率进行实证分析。关键词：DEA；一带一路；公共基础设施；AbstractThe"thebeltandroadinitiative"strategyisagreatinitiativeofPresidentXiJinpingtojointlybuildthe"NewSilkRoadEconomicBelt"and"21stCenturyMaritimeSilkRoad"whenheattendedKazakhstanandIndonesiaonSeptember10,2013.Asanindispensableprovinceof"thebeltandroadinitiative",ShaanxiProvinceshouldseizetheopportunityandfocusonimprovingtheinvestmentefficiencyofpublicinfrastructure,whichplaysakeyroleintheassessmentandadjustmentoftheprovince'sinvestment.Basedonthedataofpublicinfrastructurefrom2007to2018,thispaperusesdataenvelopmentanalysis(DEA)toconstructtheevaluationindexofinput-outputefficiencyofpublicinfrastructureinShaanxiProvince,andusescomparativeanalysismethodtoobtaintheinvestmentdifferenceofpublicinfrastructureinShaanxiProvincebeforeandafterthestrategyisputforward,andmakesempiricalanalysisontheinvestmentefficiencyunderthebackgroundof"thebeltandroadinitiative".Keywords:DEA；;Thebeltandroadinitiative;Publicinfrastructure目录1绪论..............................................................................................................................11.1研究背景..................................................................................................................11.2研究目的..................................................................................................................11.2.1研究目的...............................................................................................................11.3文献综述1.4研究思路..................................................................................................................32公共基础设施投资效率相关理论42.1.1公共基础设施的定义................................................................................................42.2公共基础设施的相关研究现状................................................................................52.2.1交通现状..........................................................................................................53实证分析.........................................................................................................................53.1指标选取.................................................................................................................53.2数据的收集和处理..................................................................................................53.2.1数据来源..........................................................................................................63.2.2数据处理..........................................................................................................63.3实证结果分析..........................................................................................................74投资效率综合评价.......................................................................
