为什么有些国家不承认我国的市场经济地位？

完全赞同啊，看看那些央企，垄断的行业。
不完全否认央企，它们的贡献也不小，但相对于民营企业来说
还是差远了。
       那么多的民营企业需要在证券市场融资，但偏偏把名额给了国企
害得许多民营企业跑到国外去上市了。

是否承认是市场经济，我认为还是国家利益间的博弈，对本国有好处，它就承认你，没好处，就不承认你。当然中国目前市场经济不够完善，行政干预过度，干预经济可能短期会有益处，但长期的问题并没有看到，市场经济更应该靠制度还规制，而不是更多的行政手段。

为何有些国家 承认我国的市场经济地位？

换做我也不承认。那么多民企小企业什么时候替代国企了再说吧。

It totally depends on the fact, not the attitude.

说明我们国家的太有特色了！

因为 政 府 政策对市场的干预太多，我国的很多企业运行不是按照完全自由竞争的规律运行，而是由太多人为操纵。数据造假几乎成风，比如保险行业，美国的精算师来到中国就无从下手，科学的计算方法对于人工制造的数据，只能是巧妇难为无米之炊啊！这样的人造市场，人家怎么会承认呢？！再者说，那些承认我们是市场经济的，大多是政治原因吧，我们不谈政事，在此不解释。楼主观察下承认我国市场经济的国家与我国的外交关系即知。

http://en.wikipedia.org/wiki/Market_economy
A market economy is an economy in which the prices of goods and services are determined in a free price system.[1] This is often contrasted with a fixed price system.
Market economies can range from hypothetically pure laissez-faire variants to an assortment of real-worldmixed economies, where the price system is under some state control or at least heavily regulated. In mixed economies, state-directed economic planning is not extensive enough to constitute a planned economy.
In the real world, market economies do not exist in pure form, as societies and governments regulate them to varying degrees rather than allow self-regulation by market forces.[2][3] The term free-market economy is sometimes used synonymously with market economy,[4] but, as Ludwig Erhard once pointed out, this does not preclude an economy from having social attributes opposed to a laissez-faire system.
The term used by itself can be somewhat misleading. For example, the United States constitutes a mixed economy (substantial market regulation, agricultural subsidies, extensive government-funded research and development,Medicare/Medicaid), yet at the same time it is foundationally rooted in a market economy. Different perspectives exist as to how strong a role the government should have in both guiding the market economy and addressing the inequalities the market produces. This is evidenced by the current lack of consensus on issues such as central banking, and welfare.
It is also possible to envision an economic system based on independent producers, cooperative, democratic worker ownership and market allocation of final goods and services; the self-managed market economy is one of several proposed forms of market socialism.[5]
Like many economies, the market economy depends on the division of labor. Some think prices in a market economy are set by supply and demand.
如果承认中国的市场经济地位，美国对中国的产品进行反倾销调查时就要以中国国内同类产品价格作为调查参考。如果不承认中国的市场经济地位，美国对中国的产品就会以其他同等经济条件国家产品价格作为调查参考。
希望这些能对楼主有所启发

我想举个例子来说，市场经济下按理说想买房是个人的自由，但是中国ZF却非要干涉，市场经济最起码是市场有需求同时供应也跟得上就能成交，但在中国却不可以啊。
