地区间经济的非均衡发展会导致价格水平差异,中等发达地区会出现工业消费品价格高于其他地区的现象,其形成机制与“中等收入陷阱”所体现的问题有类似之处。本文基于国内的要素流动情境对“巴萨模型”加以拓展,并从产品制造生产和销售服务两大环节分析消费品价格的构成。结果表明,当生产率提升速度随着技术追赶、差距缩小而减缓,且劳动力跨部门流动存在障碍时,城市工业消费品价格与当地经济发展水平之间会呈现倒U型的非线性关系,而生鲜农产品价格则更多地取决于销售环节的要素成本;减少物流成本无法改变地区间价格的对比关系,但有助于降低商品价格。基于2012-2013年56个城市、41种商品实际价格的短面板计量分析印证了理论推断。由此表明,要落实协调发展理念,就应促进要素、产品的自由流动,转变导致同质化的“跟风”式区域经济发展方式。
The unbalanced economic development among different regions leads to the difference in price levels. The phenomenon that the prices of industrial consumer goods are higher in other developed regions than in other regions appears. The formation mechanism is similar to that reflected in the “middle income trap.” This article expands the “Barcelona model ” based on the flow of elements in the country and analyzes the composition of consumer goods prices from the two aspects of product manufacturing and sales and service. The results show that when the rate of productivity increase slows down with the technology catching up and the gap narrows, and there are obstacles in cross-sector labor mobility, there will be an inverted U-shaped nonlinear relationship between the prices of urban industrial consumer goods and the local economic development. However, The price of agricultural products is more dependent on the factor cost of the sales process. Reducing the cost of logistics can not change the inter-region price comparison but helps to lower the commodity prices. Based on the short-panel econometric analysis of the actual prices of 41 commodities in 56 cities in 2012-2013, theoretical inferences are confirmed. This shows that in order to implement the concept of coordinated development, we should promote the free flow of elements and products and lead to a homogenized “follow suit” approach to regional economic development.
