消费升级与经济高质量发展:以长江经济带108个地级市为例

Consumption Upgrading and High-quality Economic Development: Examples of 108 Prefecture-level Cities in the Yangtze River Economic Belt

“消费升级”是长江经济带乃至我国城市实现经济高质量发展的重要支撑。采用SBM函数和ML指数测度2006—2019年长江经济带108个地级市的绿色全要素生产率,并以此来衡量经济质量发展水平,进而构建模型实证检验消费升级对城市经济高质量发展的影响。研究发现:(1)长江经济带绿色全要素生产率水平整体呈波动上升趋势,其中下游地区城市绿色全要素生产率增长领先,上游次之,中游最低。(2)消费升级既可直接推动城市经济高质量发展,也可通过促进产业结构高级化,间接推动城市经济高质量发展。(3)消费升级对下游城市经济高质量发展水平影响作用最大,其后依次为中游城市和上游城市。最后,本文从提高居民收入水平、优化区域产业结构、协同做强消费市场等方面提出对策建议。

“Consumption upgrading” is an important support for the Yangtze River economic belt and even Chinese cities to achieve high-quality economic development. In this paper, SBM(slack based measure) directional distance function and ML(Malmquist Luenberger) index are used to measure the green total factor productivity of 108 prefecture level cities in the Yangtze River economic belt from 2006 to 2019, so as to measure the level of economic quality development, and then build a model to empirically test the impact of consumption upgrading on the high-quality development of urban economy. The study found that:(1) the overall level of green total factor productivity in the Yangtze River Economic Belt showed a fluctuating upward trend, in which the growth of green total factor productivity in cities in the lower reaches took the lead, followed by the upper reaches, and the lowest in the middle reaches.(2) Consumption upgrading can not only directly promote the high-quality development of urban economy, but also indirectly promote the high-quality development of urban economy by promoting the upgrading of industrial structure.(3) Consumption upgrading has the greatest impact on the high-quality economic development level of downstream cities, followed by midstream cities and upstream cities respectively. Finally, this paper puts forward countermeasures and suggestions from the aspects of improving residents’ income level, optimizing regional industrial structure and synergistically strengthening the consumption market.
