The fourth part, through an analysis of human resources state of the Northeast, we think the human resources of the Northeast have the following several subject problems: The teenage labor population is too big in specific gravity, unfavorable to the sustainable development of economy; Human resources in urban and rural areas to distribute unbalanced, countryside of the right age to overpopulate , can't meet demands of urban economy development , form the labor force of leaving unused at the same time , cause the waste of the human resources ; Human resources industry distribution is unreasonable, the Northeast human resources distribution between the industry of human resources concentrates on primary industry mainly, proportion is too big, and the labor productivity of primary industry is relatively low, do not have enough ability to make the human resources shift to the secondary and tertiary industries, so seem the secondary and tertiary industries to be delayed effect enough.

第四部分，通过对东北地区人力资源状况的分析，我们认为东北地区人力资源存在以下几个主要问题：未成年劳动人口比重过大，不利于经济的可持续发展；人力资源城乡分布不均衡，农村中适龄劳动人口过多，不能满足城市经济发展的需要，同时形成闲置劳动力，造成人力资源的浪费；人力资源产业分布不合理，东北地区人力资源在产业间的分布主要集中在第一产业，比重过大，而且第一产业劳动生产率较低，没有足够的能力使人力资源向第二、三产业转移，因此显得第二、三产业后劲不足。
