2022年，預(yù)計全市地區(qū)生產(chǎn)總值超過1.2萬億元，一般公共預(yù)算收入可比增長8%，固定資產(chǎn)投資增長5%，社會消費品零售總額達到4820億元。出臺助企紓困25條政策，為中小微企業(yè)提供擔保貸款168億元，減稅退稅降費超過1000億元，幫助3.8萬家中小微企業(yè)及個體工商戶融資527.9億元，市場主體增至149.7萬戶。發(fā)放消費券2.17億元，新引進商業(yè)品牌首店55家。260個市級重點項目完成投資2320.8億元。新增進出口實績企業(yè)1656家，預(yù)計全年完成進出口2190億元、同比增長15%左右，跨境電商進出口額增長50%以上。預(yù)計全市地區(qū)生產(chǎn)總值超過1.2萬億元，一般公共預(yù)算收入可比增長8%，固定資產(chǎn)投資增長5%，社會消費品零售總額達到4820億元。
中國社會科學(xué)院數(shù)量經(jīng)濟與技術(shù)經(jīng)濟研究所與社會科學(xué)文獻出版社2022年12月13日共同發(fā)布的《經(jīng)濟藍皮書：2023年中國經(jīng)濟形勢分析與預(yù)測》預(yù)計，2023年中國經(jīng)濟增長5.1%左右，呈現(xiàn)進一步復(fù)蘇態(tài)勢。具體到地方層面，24座萬億GDP城市中，2023年GDP增速目標，濟南是5.5%以上。除濟南GDP增速目標與上年持平外，其余5座城市2023年GDP增速目標較上年均有所下調(diào)。不過，復(fù)蘇仍是2023年經(jīng)濟的主旋律，相較于2022年GDP實際表現(xiàn)，2023年的目標仍是樂觀的。數(shù)據(jù)顯示，從2022年地區(qū)生產(chǎn)總值總量來看，濟南預(yù)計超過1.2萬億元。
