Research On The Influence Mechanism And Contribution Of Logistics Industry To Economic Growth In Jilin Province

With the progress of civilization and the development of society,commodity trade continues to prosper,the market division of labor is more refined,and the logistics industry as a new service industry has developed by leaps and bounds.Similarly,the development of the logistics industry also drives the development of the regional economy.Based on the existing data,this paper studies the transmission mechanism and contribution of Jilin Province’s logistics industry to regional economic growth,and draws certain conclusions and policy recommendations.This paper introduces three potential intermediary variables,namely production cost,transaction cost and technological innovation,to discuss the principle and way of harming the future development of the logistics industry to economic development.The three variables of technological innovation have a significant positive mediating effect in the large impact of logistics industry on economic growth.Among them,technological innovation has a positive role in promoting economic growth,which is consistent with many existing research conclusions.The indices a and b in the detection of the intermediary effect of product costs and transaction costs are both positive numbers.The visual understanding is that the future development of the logistics industry will increase product costs and transaction costs,while the increase in product costs and transaction costs will improve economic development.,This is inconsistent with the forecast that the future development of the logistics industry can reduce product costs and transaction costs.This article believes that the future development of the logistics industry has improved the compressive strength of industry competition among companies.In order to better win in the industry competition And the choice of cheap countermeasures caused.Through the stationarity test,co-integration test,Granger causality test,vector autoregressive model,impulse response and variance decomposition of the data model to analyze the logistics network mileage,cargo turnover,value added of the logistics industry,and the impact of different logistics factors on the economy of Jilin Province The contribution and driving effect of growth,and the contribution rate and driving force of the logistics industry to Jilin Province’s economic growth in each year from1997 to 2020 are calculated by formulas,and the contribution of Jilin Province’s logistics industry to economic growth is determined..
