中国对外贸易遵循比较优势了吗?

Is the Chinese Export Consistent with the Comparable Advantage?

本文将居民消费、投资、政府支出、出口、进口视为产品,将劳动和资本视为原始投入,利用我国1994～2010年31个省市区的相关数据估计了超越对数GDP函数的斯托尔珀—萨缪尔森效应和雷布津斯基效应,来验证比较优势在中国的适用性.本文发现进出口产品价格上升时都会致使劳动力工资上涨；另外,本文发现当资本存量增加时,从理论上按照赫克歇尔—俄林模型的预测劳动密集型产品的出口数量应该减少,但结果显示却是增长,对此可能的解释是政策上的出口鼓励和作为资本密集型产品的出口增加导致.本文的实证结果基本与赫—俄理论相符.

In this article, consumption, investment, government spending, exports and imports are considered as products while labor and capital are regarded as original inputs. The authos use the relevant data of 31 provinces of China from 1994-2010 to estimate the Rybczynski effect and the Stolper-Samuelson effect of the translog GDP function. We find that when the prices of both import and export increase, wage will always go up, and that when capital stock is enlarged, theoretically, the quantity of exports of China which include a majority of labor-intensive products should decrease according to Heckscher-Ohlin model, however, the results show the opposite. The possible reasons for this phenomenon may be China＇ s favorable policy of exporting and the increasing quantity of capital-intensive products in exports.
