日前，著名经济学家董辅就有效需求的体制障碍发表了自己的观点。他指出，从１９９８年起，我国开始实行扩张性宏观经济政策，之所以尚未走出通货紧缩的困境，最重要的是经济体制方面的障碍。受体制影响，许多企业，特别是国有企业开工不足，利润的增长不快甚至出现亏损增长，? Recently, Dong Fu, a famous economist, expressed his own views on the institutional obstacles to effective demand. He pointed out: Since 1998, China has embarked on an expansionist macroeconomic policy and has not yet out of the plight of deflation. The most important one is the obstacles in the economic system. Affected by the system, many enterprises, especially state-owned enterprises, are under-employed, their profits are growing at an unpleasant profit, or even losing money.
