Data limitations arising from non-transparency in military expenditure
reporting impose significant constraints on economists studying count
ry and comparative developments in this field. This article focuses on
the case of China. It reviews the recent literature on China's milita
ry expenditure, examines the variance in published estimates, and iden
tifies three factors which help explain the variance: budgetary falsif
ication; non-budgeted PLA revenue; and the US dollar purchasing-power
parity of the yuan. Conclusions emphasize important policy implication
s of such variance and suggest a more active role for defence economis
ts in a field of research generating considerable attention from inter
national relations scholars.
