贫富差距过大、无害需求不足与当前世界经济危机

摘要

It has been proved by lots of historical facts that the discretionary aggregate demand management policy pro-posed by Keynes on the basis of insufficient effective demand cannot make economy growth smooth and stable; however, it has become one of the factors that lead to economic crisis. As for the long-term smooth growth of economy, the determinant is "harmless demand", rather than the ambiguous "effective demand". To narrow the wealth gap to a reasonable range and in-crease the harmless demand while downsize the harmful demand is the fundamental way of ensuring the long-term stable eco-nomic growth.%历史事实表明，凯恩斯基于“有效需求不足”所提出的“相机抉择”式总需求管理理论并没有保证经济的稳定发展，凯恩斯主义在全球的过度实施反而成为经济危机的幕后推手之一。就经济的长期稳定发展而言，起决定性作用的是无害需求，而不是笼统的有效需求。将贫富差距控制在合理范围之内，用增加无害需求、限制有害需求的方式来扩大总的有效需求，这将是长期中保证经济稳定增长的根本途径。
