Does Skill Content Explain Total Trade and Intra‐Industry Trade?
比较了不同技术假设下贸易流的技能内容检验结果，发现考虑国家间技术异质性并纳入产业内贸易后，实际技能内容与要素禀赋预测更吻合；禀赋差异能解释净贸易和垂直产业内贸易，但不能解释水平产业内贸易。
Abstract This study compares the results of skill content tests for types of trade flows under alternative assumptions about the technologies used to produce imports and exports. For trade between high‐ and middle‐income countries, we show that the match between the actual skill content of trade and that predicted by endowments in a Heckscher–Ohlin–Vanek framework improves substantially if technological heterogeneity across countries is allowed for and if the factor content of intra‐industry trade is included with that of inter‐industry trade. Endowment differences are important in explaining net trade and vertical intra‐industry trade, but not horizontal intra‐industry trade.
