长江经济带制造业服务化梯度推进路径研究

作为我国承东启西极其重要的经济纽带，长江经济带汇聚了一大批优秀的制造业企业，是中国的“制造工厂”，作为国家战略发展重点，长江经济带的制造业亟需转型升级。利用核密度分布和马尔可夫转移矩阵对长江经济带制造业服务化水平的分布和动态演进进行了分析，发现11省市制造业服务化水平整体较低，有向低水平收敛的趋势，两极分化严重，从稳态分布看，短期内将保持较大差异，难以实现均衡。再从服务化中间投入和服务化水平两个维度对11个省市的3大类制造业进行了分类，发现沿长江经济带从下游至上游呈现逐渐降低的梯度分布格局，提出了“三步走”的梯度推进路径，并结合上、中、下游的产业、资源和交通等特点，提出了制造业服务化梯度推进的合理建议。

The Path Study on the Gradient Propulsion of the Manufacturing Servitization in Yangtze River Economic Belt

As the connection of Chinese eastern and western important economic ties,Yangtze River economic belt has gathered a large number of outstanding manufacturing enterprises,is Chinese"manufacturing factory".As Chinese devel-opment strategic focus on it ,the Yangtze River Economic Belt of manufacturing industry need transformation and upgra-ding.The paper uses kernel density estimation and the Markov transition matrix to analysis the distribution and dynamic evolution of Yangtze River economic belt manufacturing servitization level,it finds that the manufacturing servitization level is low in 1 1 provinces,has the trends to gather in lower level ,and polarization is serious,see from the steady state distribution,in the short term it will remain larger difference.It's difficult to achieve balanced.Then,classified the manu-facturing servitization level from the input of intermediate service and servitization level into four parts,it finds along the Yangtze River economic belt from the downstream to the upstream has gradually reduced gradient distribution pattern, puts forward the"three-step"gradient propulsion path,combines the different area's characteristics of industry resources and transportation,and puts forward reasonable proposals to promote the gradient of the manufacturing servitization.
