摘　　要：党的十九大报告提出要强化举措推进西部大开发形成新格局。基于1978年至2019年西部地区经济发展数据,借助因素分解、构建结构性致因系数模型等方法分析西部地区经济增速放缓的结构性致因与化解机制,为其经济高质量发展提供理论依据。研究发现:改革开放以来西部地区经济增速呈倒“U”型演化轨迹,现阶段经济增速趋于放缓;西部地区第三产业劳动生产率增长率低于第一和第二产业是引发其经济增速放缓的结构性致因,作用机理表现为,西部地区产业结构调整过程中第三产业规模不断扩大,呈现服务化转型特征,较大产业规模叠加相对较低的劳动生产率增长率,导致第三产业拉低了全社会劳动生产率增长率和人均GDP增长率,并进而引发经济增速放缓;得益于生产性服务业对第三产业劳动生产率增长率正向推动作用,提出大力发展生产性服务业是化解西部地区经济增速放缓结构性致因的有效机制。The report of the 19 th National Congress of the Communist Party of China proposed to strengthen measures to promote the development of the western region to form a new pattern. Based on the economic development data of western regions from 1978 to 2019, the structural causes and mitigation mechanism of the economic slowdown in western regions are analyzed by means of factor decomposition and structural cause factor model construction, so as to provide a theoretical basis for its high-quality economic development. The research has indicated that since the reform and opening up, the economic growth rate in western China has shown an upturn “U”-type evolution trajectory, and the economic growth rate tends to slow down at the present stage. The growth rate of labor productivity in the tertiary industry is lower than that of the primary and secondary industries, which is the structural cause of its economic slowdown. The mechanism of action is that in the process of industrial structure adjustment in western China, the scale of the tertiary industry is constantly expanding, showing the characteristics of service-oriented transformation. Large industrial scale combined with relatively low labor productivity growth rate, the tertiary industry pulled down the whole social labor productivity growth rate and per capita GDP growth rate, and then led to a slowdown in economic growth. Thanks to the positive role of producer services in promoting the growth rate of labor productivity in the tertiary industry, it is proposed that vigorously developing producer services is an effective mechanism to resolve the structural cause of the economic growth slowdown in the western region.
