市场经济即需求导向型经济。近年来国际国内市场疲软，我国政府为启动经济发展而采取的“扩大内需”政策是一种积极的措施。但这种政策的效果是有限的。究其原因是政府投资比例过高，效率太低，民间投资太弱，抵消了投资的积极效应，而收入分配的不公、信用条件偏紧和改革预期的不稳定阻碍了需求的增长，为此，启动经济发展首先需要消除或减轻发展的障碍，培养发展的正常条件。 Market economy is demand-oriented economy. In recent years, the weak domestic and international markets and the policy of “expanding domestic demand” adopted by our government for starting economic development are positive measures. However, the effect of such a policy is limited. The reason is that the government investment is too high, the efficiency is too low, the private investment is too weak, offsetting the positive effect of investment, and the inequality of income distribution, the tight credit conditions and the anticipated unstable change have hindered the growth of demand. To start economic development, we must first eliminate or alleviate the obstacles to development and foster the normal conditions for development.
