Thus the paper puts forward that different forms of expression should be adopted in different fields, the results are as follows: As to the Industry involving national military security, economic security and cultural security, the state-owned capital should be in the form of single proprietorship or conditional diversification, that is to say, taking the solely state-owned company as its main body. As to the strategic industry and basic industry in the vital position to the national economy, the state-owned capital should be As to the strategic competitive industry which plays an important role in development of national economy and society, the state-owned capital account for a certain proportion with the freedom to select holding shares or taking equity participation. As to the industry related to non-strategic competitive fields, state-owned capital does not necessarily exist in the form of state-owned enterprise, it can also obtain the stock right to share the benefit, and to cooperate, even compete with other capitals appropriately.

由此提出了国有资本在不同领域应采取不同的表现形式：在涉及国家军事安全、经济安全、文化安全的产业内，国有资本只能是独资或有条件的多元化，也就是以国有独资公司为主；在关系国民经济命脉的战略产业和基础产业内，国有资本必须保持控股，即还将保留相当数量的国有企业；在对国民经济和社会发展具有重要作用的战略性竞争产业内，国有资本仍要占有一定比重，但可以根据具体情况选择控股和参股；在非战略性竞争领域的产业内，国有资本不一定必须要采取国有企业的形式存在其中，完全可以以股权的形式参与进来，适度与其它性质的资本开展合作与竞争。
