互联网医疗信息溢出与中国居民就诊选择一一基于CHNS混合截面数据的实证研究刘宸周向红同济大学经济与管理学院摘要:制度、价格、更疗保险是分级诊疗的研究焦点,而“信息”的价值未被足够重视。在互联网时代,医疗信息呈现溢岀态势。木文关注了互联网医疗信息溢出与居民就诊选择的关联。研究基于医疗知识的异质性构建了理论假设,而后利用2006—2011年CIINS混合截面数据和多项Logit模型进行了实证分析。结果显示,互联网医疗信息溢出引发了个体就诊选择的两极化,突出表现为自我诊疗、高等级医院对基层医疗卫生机构患者的分流。互联网打破了普通疾病的知识壁垒,产牛了自我诊疗对基层医疗卫牛机构的替代效应,不过疑难杂症及重大疾病的知识垄断不会被消解,自我诊疗无法替代高等级医院。信息供给的增加也为决策带来了“噪音”,加剧了正规医疗机构就诊的“趋高倾向”。本文不仅将“信息”纳入了医疗卫生需求的研究分支,也为分级诊疗诱导机制的设计提供了“互联网+”的思考方向。关键词:分级诊疗;互联网;医疗信息溢出;就诊选择;作者简介:刘宸(1990-),男,同济大学经济与管理学院博士研究生,研究方向:卫生经济学;E-mail:1iuchen_tj@tongji.edu.cn;作者简介:周向红(1968-),女,同济大学经济与管理学院教授、博士生导师,研究方向:公共管理、公共政策分析。收稿日期:2017-03-28基金:国家自然科学基金面上项冃(71473177)---本文来源于网络,仅供参考,勿照抄,如有侵权请联系删除---IllMedicalInformationSpilloversandHea1thCareChoiceofChineseResidentsintheInternetEraAnEmpiricalResearchBasedonCHNSLiuChenZhouXianghongSchoolofEconomicsandManagement,TongjiUniversity;Abstract:Institution,priceandmedicalinsurancearethecommonfocusesofthepilotandacademicresearchofhierarchicalmedicalsystem,butthevalueofinformationisignored.TntheInternetera,medicalinformationspilloversarepresented.TheobjectiveofthispaperistoanalyzetheimpactofInternetmedicalinformationspilloversonChineseresidents'choiceofhealthcare.Basedontheheterogeneityofmedicalknowledge,thisstudyconstructsthetheoreticalhypotheses.ThenthesehypothesesareempiricallytestedwithpooledcrosssectiondatafromCHNS2006—2011andMultinomialLogitModel.Researchshowsthat,intheInternetera,medicalinformationspillovershaveledtothepolarizationofresidents'healthcarechoice,whichselfdiagnosisandhighlevelhospitalshaveshuntedthepatientsintheprimaryhealthcareinstitutions.TheInternethasbrokenthebarrierofknowledgeaboutcommondiseases,whichproducesasubstituteeffectofselfdiagnosisonprimaryhealthcareinstitutions.However,themonopolyofknowledgeaboutseriousdiseaseshasnotbeendispelledbytheInternet,andthusselfdiagnosiscannotsubstitutehighlevelhospitals.Moreover,theincreaseinthesupplyofinformationhasbroughtsomenoisestothedecision-meiking,whichcausesindividuals'increasingpreferenceforhighlevelhospitalsinthechoiceofformalhealthcareinstitutions.Limitedbytheavailabilityofdata,theresearchuseswebsurfingandinternetaccessathomeasproxyvariables.Inspiteofintrinsiclogicandself-consistency,thesevariablesdon'ttotallyequatetoInternetmedicalinfonnationspillovers.Anotherproblemisendogeneity,whichmeanswebsurfingandInternctaccessathomearcnotrandomevents.Strictcausalinferenceneedsfurtherresearch.Thispapernotonlyembedsinformationintotheresearchofhea1thcaredemand,butalsoprovidesathinkingdirectionofInternetplusforthedesignofinducementmochanisminthehierarchicalmedicalsystem.---本文来源于网络,仅供参考,勿照抄,如有侵权请联系删除---Keyword:HierarchicalMedicalSystem;theInternet;MedicalInformationSp订lovers;HealthCareChoice;Received:2017-03-281引言随着生活...
