摘　　要：跨区域商品价格差被认为是研究国内区际贸易的有效替代指标,文章首先以我国12个样本城市六大类商品价格为考察对象,经回归分析认为:除了距离等控制因素外,"樊纲指数"和"政府支出占GDP的比率"较好地解释了我国六大类商品价格偏差的边界效应,说明市场化进程落后的地区更可能筑起商品贸易的政策壁垒,而具有"父爱"意识的政府在高财政支出比率情形下更有能力实施保护战略,从而验证了文章的边界效应假说。实证分析还获取了两个层次的边界效应(包括品类边界效应和省份边界效应),并作为市场一体化指标被纳入文章的经济增长方程进行回归;结果显示:地方保护壁垒造成的省份市场分割,影响到保护战略实施省份的自身经济绩效。Cross-regional price difference is regarded as a good substitute index of domestic inter-regional trade. Based on the prices of 6 types of commodities in 12 sample cities, the paper uses regression analysis and concludes that Fangang index and the percentage of government expenditure on GDP can provide better explanations of boundary effects of price differences of 6 types of commodities besides such controlling factors as distance. It is apt to form trade barriers in the areas with slow market-oriented reform and to implement protection strategy by the local governments, so the assumption of boundary effect has been verified. Through the regression analysis of economic growth by introducing market integration index, it indicates that provincial market segmentation has impacts on economic performance of provinces who implement local protection strategy.
