Considering that there exist both a large state sector and a fast expa
nding private sector in the Chinese economy, we establish two-sector m
odels to depict and investigate the macroeconomic operation of the Chi
nese economy. The models embody a basic feature of the Chinese economy
: the rigidity of wage rates and employee numbers in state-owned firms
. Comparative static analysis of economic equilibrium shows that the e
xpansion of nominal aggregate demand will raise price index and increa
se real aggregate income. On the other hand, if the government enlarge
s the difference between the wage rates of 'working workers' and 'wait
ing workers', the economy will have a higher price index and a lower r
eal aggregate income.
