以食用各种水生动物和小粒型植物果实为主的广谱经济，以往学界都认为它是旧石器向新石器时代过渡阶段的重要特点。但长江流域及以南地区已有的考古发现与本文的研究表明，直到新石器时代中期，广谱经济都是人类食物的主要来源，并为稻作的起源和发展创造了条件。新石器时代晚期，由于人地关系不断紧张，自然食物的来源日趋减少，广谱经济的原有地位才最终被稻作农业所取代。

The broad-spectrum economy, in which human food basically consisted of various aquatic animals and granular fruits, was widely considered as one of the most important traits during the transition from the Paleolithic Age to the Neolithic Age. However, after careful reflection on the archaeological discoveries in the Yangtze River basin and its southern area, this paper finds that the broad-spectrum economy had always been the main source of human food until the Mid-Neolithic Age; in the mean while, it contributed greatly to the origin and development of the rice agriculture. In the late Neolithic Age, due to the increasingly tense relationship between people and earth and the decrease of natural food resource, the broad-spectrum economy was eventually replaced by the rice agriculture.
