Abstract: By using Taiwan’s census firm data, this paper estimates and tests the variable returns
to scale hypothesis for aggregate manufacturing and two-digit industries. An e -
ciency measure is constructed to further examine the size-e ciency relations among
two-digit industries. Analysis indicates that increasing returns exist at the aggregate
manufacturing level and its magnitude is higher for exporting firms than for nonexporting firms. Moreover, trade is beneficial only for small firms. However, the
property of increasing returns diminishes for most of the industries at the two-digit
level, particularly for the exporting firms. This sharp comparison between aggregate
and two-digit level results suggests that trade is conducive to productivity, and
provides an indication of the specific form of technology spillovers among firms and
across industries. Further investigation of the relationship between productive e -
ciency and firm size renders the result that optimal firm size is small for exporting
firms in most industries, particularly in the most export-oriented ones. The technology
spillover e€ ect among firms and across industries is likely the reason for being small
and e cient. Our results also indicate that an industry-wide spillover e€ ect across
firms within the same industry is roughly one-sixth of the firm-specific export-induced
learning e€ ect. Findings in this study provide valuable insight into Taiwan’s economic
development and also provide a development strategy for developing countries to
