从边际产业内贸易角度,分别运用A指数和S指数对1992—2008年间中美19个行业的工业制成品贸易调整成本进行研究,并进行Daniels检验。研究结果表明,中美工业制成品绝大多数处于产业间贸易,总体调整成本较高;高技术产业的贸易调整成本相对较低;中等技术产业的调整成本呈逐渐减少趋势;低技术产业的调整成本一直处于相对较高的状态。这些结论为国家制定相关经济政策提供了决策参考。
From the perspective of marginal intra-industry trade, the A-index and S-index were respectively used to study the adjustment costs of trade in industrial products between 19 industries in China and the United States from 1992 to 2008, and the Daniels test was conducted. The results show that the vast majority of industrial products in China and the United States are in intra-industry trade with high overall adjustment costs; the trade adjustment costs of high-tech industries are relatively low; the adjustment costs of medium-tech industries are gradually decreasing; and that of low-tech industries Adjustment costs have been relatively high. These conclusions provide the decision-making reference for the state to formulate relevant economic policies.
