Abstract: The construction of unified market of Chengdu-Chongqing economic circle will provide strong support for promoting the coordinated economic development of Chengdu-Chongqing economic circle and narrowing the regional development gap in China. The paper analyzes Chengdu-Chongqing economic circle market integration construction of space and time evolution, finds the fact that if the current Chengdu-Chongqing economic circle commodity market integration process is faster, then the factor market integration process is relatively slow, but the cities between goods and elements market integration level gap are widened, commodity and labor market presents obvious space agglomeration situation. On this basis, the influence factors of the market integration in Chengdu-Chongqing economic circle are empirically tested through the spatial measurement model. The results show that the market size increases by strengthening the economic ties between other cities to promote other city market integration, human capital accumulation to promote the city market integration and has a significant positive space spillover effect, the expansion of the city market integration has promoting effect, and through siphon effect, strengthens the other cities’ market segmentation. The paper may help provide relevant policy reference for promoting unified market in Chengdu-Chongqing economic circle.

摘要： 成渝地区双城经济圈统一市场建设为推动成渝地区双城经济圈经济协调发展、缩小区域发展差距提供坚强支撑。梳理分析成渝地区双城经济圈市场一体化建设的时空演变，提出成渝地区双城经济圈商品市场一体化进程较快而要素市场一体化进程相对缓慢，但各城市间商品和要素市场一体化水平差距有所扩大，商品和劳动力市场呈现明显的空间集聚态势。通过空间计量模型实证影响成渝地区双城经济圈市场一体化的因素，结果表明，市场规模提升通过强化与其他城市间的经济联系推动其他城市市场一体化，人力资本积累促进本城市市场一体化，且具有显著的正向空间溢出效应，人口规模扩张对本城市市场一体化具有促进作用，但通过虹吸效应强化其他城市实施市场分割的动力，为推动形成成渝地区双城经济圈统一市场提供政策参考。
