That marks a new stage of CP--vigorous promotion period. Since then, CP demonstration had changed from enterprise level to regional and industrial level. And governments focus had shifted from policy study to policy making. In 1999 accord ing to the leg islation principles of the gth NPC Stand ing Committee.
