20世纪中期以前,民族主义与普遍主义国际私法思想呈现出对峙的局面。随着比较法学派的兴起,这种对峙不断缓和并趋于统一和融合。这种统一和融合的趋势主要表现在两个方面:一是商人法在国际私法中的地位和作用受到重视,二是北美自由贸易联盟和欧盟的不同的国际私法一体化路径所达到的异曲同工的效果。 Before the middle of the 20th century, the nationalist and universal private international law of thought presented a standoff. With the rise of the comparative law school, this confrontation has been eased and tends to unite and converge. This trend of unification and integration mainly manifests itself in two aspects: First, the position and role of the merchant law in private international law are valued; second, the similarities reached between the North American Free Trade Association and the EU in the integration of different private international law approaches effect.
