Measuring the Competitive Threat from China

In recent years there has been a growing literature that analyses the threat which Chinese exports pose to the exports of other developing countries. The paper provides a critique of the standard measures of export similarity which have been used to estimate the threat from China in these studies. Two alternative indices, the static and the dynamic index of competitive threat, are developed and estimated for 18 developing countries and compared with estimates for the standard measures. It is shown that the latter tend to underestimate the extent to which countries are threatened by China. They also distort both the rankings of countries according to the extent to which they face competition from China and the direction of change in the competitive threat over time.
