摘　　要： 跨区域商品价格差被认为是研究国内区际贸易的有力替代指标,本文以我国12个样本城市六大类商品价格为考察对象,回归结果显示,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,验证了本文的边界效应假说。实证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本文的经济增长方程进行回归;"改革"和"开放"两变量控制后,结果显示地方保护壁垒造成的省际市场分割,影响到保护战略实施省份的自身经济绩效。 The inter-regional commodity price is considered as a powerful indicator to study domestic trade. This article chooses 12 cities in China to observe their product prices. The regression has been made to show that the factors such as ＂Fan Gang Index＂ and the rate of government expenditures to GDP in China are better to explain the price deviations for the six major types of commodity in addition to the control variable of distance. The evidence of the border effect shows that the less-developed areas are more likely to build trade barriers, and if keeping a higher percentage of expenditure, the governments with the protection may have a larger power to implement the protection strategy, which can verify our border effect hypothesis. The empirical analysis has obtained two levels of border effects （including both the category border effects and the province border effects）, which as market indicators have been integrated into the economic growth equation. The regression shows that the provinces haven＇t developed their economy well by the protection barriers.
