Research On The Impact Of The Agglomeration Of Producer Services On Economic Growth In Northeast China

With the change of the world economic development trend,the proportion of service industry,especially producer service industry,is increasing in China,and its contribution to economic growth is also increasing.It has become the main driving force of current economic growth,and the agglomeration of producer service industry plays an important role in enhancing regional competitiveness and adjusting industrial structure.The economic development of Northeast China once fell into a dilemma.Although some achievements have been made after a series of industrial restructuring,the development of producer services is still in a backward stage,with problems such as small overall scale,low level of agglomeration and unreasonable structure.In recent years,the agglomeration scale and level of producer services in Northeast China have been expanding,which brings new opportunities for economic growth in Northeast China.Therefore,the current research should be based on the actual situation of economic development in Northeast China,comprehensively analyze the development status and agglomeration level of producer services,explore the specific impact of agglomeration on economic growth,and put forward reasonable suggestions for the revitalization of northeast economy.The purpose of this paper is to understand how the agglomeration of producer services affects the economic growth of Northeast China.First of all,on the practical level,the paper analyzes and calculates the development status and agglomeration level of producer services in Northeast China.Then,on the theoretical level,combined with the economic growth effect and crowding effect of agglomeration,this paper comprehensively analyzes the mechanism of agglomeration affecting economic growth.On the basis of current situation analysis and theoretical analysis,this paper introduces the agglomeration level of producer services into the C-D production function,constructs the static panel model(FGLS model)and the dynamic panel model(VAR model)for empirical analysis,and analyzes the dynamic impact of the agglomeration level of producer services on economic growth through the impulse response function,and obtains the producer services in Northeast China The short-term and long-term effects of agglomeration on economic growth.Through theoretical and empirical analysis,the following conclusions are drawn: first,in general,the productive service industry in Northeast China develops rapidly,but there are still problems such as small scale,uncoordinated industries,unreasonable industrial structure and lack of high-tech professionals;second,the productive service industry in Northeast China has formed agglomeration phenomenon,but the overall level of agglomeration is relatively high Third,the agglomeration of producer services can promote the economic growth of Northeast China,and this role has a long-term effect,the two are long-term dynamic equilibrium relationship.Finally,according to the conclusion,this paper puts forward countermeasures and suggestions for Northeast China,such as expanding the scale of agglomeration,adjusting the internal structure,training professional talents,etc.,and promotes the coordinated and stable development of Northeast China's economy by promoting city linkage and intergovernmental cooperation.
