摘要2020年，中国开启了经济内循环为主，国际国内双循环相互促进的新发展模式，这是中国经济以规模发展转变到以质量发展的必然选择。“十四五”期间，国家就提出了东北全面振兴取得新突破的战略目标，为东北老工业基地带来新机遇。尽管多年来，政府一直在推行“重振”的政策，但成效并不明显，究其根源，还是体制落后与缺少创新力。本文从五个方面对东北老工业基地所面临的问题进行了分析，并就如何应对这些问题提出了一些新的对策。一要积极推动国有企业的改革，使现有的人才、技术和其他创新资源得到充分利用；二要加强对创新型、科技型民营企业的扶持，推动新技术、新产业的迅速发展。四十多年的发展历程证明，珠江、长江等地的迅速发展是以开放为中心的区域经济发展的典范。在目前“双循环”格局下，东北老工业基地既要参与国内经济合作，又要进行国际合作。本文从双循环发展格局出发，提出东北老工业基地加强同东北亚国家的经贸合作，在资金、技术、管理等方面利用好日本、韩国和俄罗斯等国家的资金、技术与市场，加快“一带一路”建设等新机遇。积极推进东北地区开放合作，优化东北老工业基地的产业布局，是“十四五”时期东北地区振兴的一个重要任务。关键词：双循环发展格局，东北老工业基地，开放合作，新机遇NewOpportunitiesforOpeningandCooperationofNortheastOldIndustrialBaseunderDoubleCirculationDevelopmentPatternAbstract:In2020,Chinawilllaunchaneweconomicdevelopmentmodelfeaturinginternalcycles,withbothinternationalanddomesticcyclesreinforcingeachother.ThisisaninevitablechoiceforChinatotransformitseconomyfromscaletoquality.Duringthe14thFive-yearPlanperiod,thestateputforwardthestrategicgoalofachievingnewbreakthroughsintheoverallrevitalizationofnortheastChina,bringingnewopportunitiestotheoldindustrialbaseinnortheastChina.Althoughthegovernmenthasbeencarryingoutthepolicyof"revitalizing"formanyyears,theresultsarenotobvious,andtherootcauseisthesystemandsystem,lackofinnovation.ThispaperanalyzestheproblemsfacedbytheoldindustrialbaseinnortheastChinafromfiveaspectsandputsforwardnewstrategiestosolvetheproblems.First,promotethereformofstate-ownedenterprisesandmakefulluseoftheexistingtalent,technologyandotherinnovativeresources.Second,strengthensupportforprivate,innovativeandtechnology-basedprivateenterprisesandpromotetherapiddevelopmentofnewtechnologiesandindustries.Morethan40yearsofdevelopmenthasprovedthattherapiddevelopmentofthePearlRiver,Underthecurrentpatternof"doublecirculation",northeastoldindustrialbaseshouldnotonlyparticipateindomesticeconomiccooperation,butalsocarryoutinternationalcooperation.Accordingtothenewdevelopmentpatternofdoublecirculation,thispaperputsforwardnewopportunitiesforthedevelopmentoftheoldindustrialbaseinnortheastChina.Inotherwords,northeastoldindustrialbaseshouldstrengtheneconomicandtradecooperationwithNortheastAsiancountries,takeanactivepartintheeconomiccooperationinNortheastAsia,andmakegooduseofthecapital,technologyandmarketofJapan,SouthKoreaandRussiaintermsofcapital,technologyandmanagement.ItisanimportanttaskfortherevitalizationofnortheastChinaduringthe14thFive-yearPlanperiodtospeeduptheconstructionoftheBeltandRoadinitiative,expandtheopening-upofnortheastChinaandoptimizeitsenterpriseandindustrialstructure.Keywords:Dual-cycledevelopmentpattern,Northeastoldindustrialbase,Opennessandcooperation,Newopportunities目录一、引言....................................................................1二、相关概念界定............................................................1（一）双循环格局含义....................................................1...
