摘要：破除阻碍全国统一大市场建设卡点堵点以纵深推进全国统一大市场建设，必须解决好各地区统一市场建设推进不平衡不协调的问题。本文聚焦商品市场维度，运用价格法对1997—2024年中国商品市场分割指数进行测算，分析全国统一大市场建设的演变规律与区域特征，为全国统一大市场的整体建设路径提供商品市场维度的经验依据。研究发现：研究期内全国商品市场分割水平呈现波动下降的趋势，市场整合取得显著成效；同时，区域市场整合水平差异明显，四大经济区市场统一程度由高到低依次为东北地区、中部地区、西部地区和东部地区。对差异来源的分析显示，区域差异是造成整体差异的主要因素，而区域内差异的贡献度较低且保持稳定。趋势演化分析发现，高分割与低分割区域均存在“粘性效应”，即区域一旦处于某种分割状态，便容易长期维持该状态。市场整合是一个“边际改进”的渐进过程，难以实现跨越式跃迁。在空间特征方面，高（或低）分割水平的地区会促使邻近地区向高（或低）分割水平转变继而产生市场分割的集聚效应。本文的研究为坚决破除阻碍全国统一大市场建设卡点堵点提供了重要的经验证据和政策启示。

Abstract: To eliminate the bottlenecks hindering the construction of the unified national market and advance its in-depth development, it is imperative to address the prominent shortcoming of unbalanced and uncoordinated progress in unified market construction across different regions.

This paper conducts a specialized study focusing on the commodity market dimension and adopts the price method to estimate the commodity market segmentation index among Chinese provincial-level regions from 1997 to 2024. It analyzes the spatiotemporal evolution rules and regional agglomeration characteristics of the unified national market construction, aiming to provide empirical evidence from the commodity market perspective for the overall construction path.

This paper finds that, in recent years, China's commodity market segmentation level has shown a fluctuating downward trend, and market integration has achieved remarkable results. However, there are obvious differences in market integration levels among regions, and the market unification degree of the four major economic regions ranks from high to low as follows: northeastern region, central region, western region, and eastern region.

The analysis of the sources of differences shows that inter-regional disparities are the main factors leading to the overall differences, while the contribution of intra-regional disparities is relatively low and remains stable. The trend evolution analysis reveals that both high-segmentation and low-segmentation regions have a “sticky effect”, which means once a region is in a certain segmentation state, it tends to maintain this state for a long time; meanwhile, market integration is a gradual process of “marginal improvement”, and it is difficult to achieve leapfrog transition.

In terms of spatial characteristics, the market segmentation level has a significant spatial assimilation agglomeration effect: Regions with high (or low) segmentation levels will drive neighboring regions to shift towards high (or low) segmentation levels, thus forming the agglomeration effect of market segmentation.

On this basis, this paper puts forward the paths and policies for the balanced promotion of regional unified market construction. This paper provides important empirical evidence and policy implications for implementing the requirements of the Proposal adopted at the Fourth Plenary Session of the 20th Central Committee of the Communist Party of China to resolutely eliminate the bottlenecks hindering the construction of the unified national market.
