有效需求依存于有效供给 ,不容忽视供给对需求的制约、促进和创造的作用.我国当前消费需求不足 ,一个被忽视或未引起足够重视的原因 ,是供给障碍.为了扩大有效消费需求 ,应重视从供给方面促进潜在的消费需求转化为现实的消费需求 ,包括调整和优化供给结构 ,提高供给质量 ,疏通供给渠道、拓宽供给空间等“,”The effective need depends on the effective supply. More attention should be paid to the effects that supply controls, improves and invents consumptive needs. The neglected reason why consumptive needs are insufficient in our country at present is the obstacles of supply. In order to enlarge the effective needs of consumption, we should promote the convertion of potential needs of consumption into real ones in respect to supply, such as adjusting and optimizing its structure, improving its quality , dredging its channels, and widenning its room.
