【摘要】：在我国向市场经济转型的过程中,如何调整国有经济的相对规模一直是一个核心问题。诚然以前的纯国有经济并不是一个最优选择,但因此转变为纯私有经济是否也会导致走向另外一个极端?本文论证以我国的初始的纯国有经济禀赋出发,希望借此来找到一个最优的国有经济在社会全部经济中的比重。本文分析国有经济的比重将从国有企业经济比重和国有资本经济比重两个方面入手。从国有企业来看,其相比于私有经济能充分利用社会分散信息的优势,国有企业经济总体上则存在信息局限,这导致市场竞争下国有企业经济比重会落至某一均衡水平,该水平构成了规范意义上的国有企业经济比重上限。当国有资本经济最优比重超过这一上限时,超出部分的国有资本应以参股私有企业的方式存在。而国有资本经济比重的确定取决于对国有资本经济优势的发挥,后者通过国有资本收益的公共福利性分配来实现,这一分配既可以替代部分税收从而节省税收成本,又为政府优化长期经济提供了一个与税收互补的新手段。该水平确定了国有资本经济比重的下限。通过上述两者的确定可以得到一个最优均衡时的国有经济的水平。本文构造了一个混合经济的Ramsey模型,以求解政府为引导出最优增长而选择的最优税率以及由之决定的最优公共支出和国有资本经济最优比重等。另外,混合经济与纯私有经济的福利比较还表明,有税收成本时,前者不论在加总消费水平还是消费结构方面均优于后者。本文结论主要说明了以我国的初始禀赋点出发,转型为纯私有经济国家并不是一个最优选择,选择一个最优的国有经济比重才能达到全民福利的最大化。
[Abstract]:How to adjust the relative scale of state-owned economy has always been a core problem in the process of transition from market economy to market economy. It is true that the former pure state-owned economy is not an optimal choice, but so the transition to a pure private economy will also lead to the other extreme? Based on the initial pure state-owned economy endowment of our country, this paper hopes to find out the proportion of an optimal state-owned economy in the whole social economy. This paper analyzes the proportion of state-owned economy from two aspects: the proportion of state-owned enterprise economy and the proportion of state-owned capital economy. From the point of view of state-owned enterprises, compared with the private economy, they can make full use of the advantages of social decentralized information, while the state-owned enterprises have information limitations in general, which leads to the proportion of state-owned enterprises' economy falling to a certain equilibrium level under the market competition. This level constitutes the upper limit of the proportion of state-owned enterprises in the normative sense. When the optimal proportion of state-owned capital economy exceeds this upper limit, the excess part of state-owned capital should exist in the form of equity participation in private enterprises. The proportion of state-owned capital economy depends on the advantage of state-owned capital economy, which is realized through the public welfare distribution of state-owned capital income, which can not only replace part of tax revenue, but also save tax cost. It also provides a new means for the government to optimize the long-term economy. This level determines the lower limit of the economic proportion of state-owned capital. The level of the state-owned economy in the optimal equilibrium can be obtained by determining the above two factors. In this paper, a Ramsey model of mixed economy is constructed to solve the optimal tax rate chosen by the government to guide the optimal growth, the optimal public expenditure and the optimal proportion of the state-owned capital economy determined by the optimal tax rate. In addition, the welfare comparison of mixed economy and pure private economy also shows that the former is superior to the latter in terms of total consumption level and consumption structure when there is tax cost. The conclusion of this paper mainly shows that the transition to a pure private economy country is not an optimal choice based on the initial endowment of our country, and the selection of an optimal proportion of the state-owned economy can maximize the welfare of the whole people.
