如果没有理解错的话,New Trade Theory是指1970s Krugman为首开创的一系列模型,
Dixit and Stiglitz (1977), Krugman (1979, 1980, 1981, 1983), Lancaster (1979) and Dixit and Norman (1980).
In general, models in this mould consider monopolistic power, economies of scale and product differentiation as determinants of international specialisation and trade flow.
其实这些模型最初是想解释IIT,而后来才一点点建立起来的.
