This paper examines bilateral intra-industry trade (IIT) in the EU dai
ry products industry during 1988-92, in order to assess whether both c
ountry specific and industry-sperific factors determine this component
of trade flows. It is shown that IIT in dairy products between pairs
of countries is negatively related to the variables indicating inequal
ity between the two countries. Two-way flows are thus more significant
, the more similar the countries are. The coefficients for the variabl
es describing industry structure suggest that the presence of large fi
rms with an absolute cost advantage over smaller firms stimulates IIT-
enhancing non-price competition. Concentration in the retail sector wa
s found to have a negative effect on IIT, which conflicts with our ori
ginal hypothesis.
