China's manufacturing sector developed according to the principle of "walking on two legs," a policy of self-reliance introduced in the 1950s. In the 1980s one leg consisted of the state-funded and state-controlled large and medium-sized plants with the most qualified personnel and the most advanced equipment. The other leg was small-scale plants using inferior equipment and large amounts of local labor. Together, the two sectors produced a wide range of industrial products. In most cases the larger plants accounted for the bulk of production, but the smaller enterprises were increasing their share and producing a significant percentage of cement, fertilizers, and farm machinery.
