Changes of Ownership of Houses in China
Ownership of houses in China has changed greatly in the past decade. In the past, most houses were stateowned. But now, private houses are everywhere. As is shown in the chart above, in 1990, the city’s houses were mainly state-owned, with a percentage of 75. This percentage became 60 in the year 1995 and then dropped sharply to 20 in 2000. At the same time, the number of private houses has soared up to 80 percent.
There are mainly two reasons that account for this rapid change. Firstly, the government has been forwarding the policy to support private houses programs. These programs have proved to be very important in developing China’s economy. Secondly, with the development of economy, people’s standard of living has risen. They want to have their own houses to satisfy their needs.
The change has enabled more people to enjoy larger living space. At the same time, people feel pressure to make more money so that they can buy their own houses.

中国住房产权的变化
在中国的房屋所有权在过去的十年中已经发生了很大的变化。在过去，大多数房屋都是公有的。但现在，私人住宅随处可见。如在1990以上，图表显示，城市的房屋主要是国有的，有75个。这个比例变成了60个1995年，然后下降到20 2000。同时，私人住房的人数已高达百分之80。
主要有两个原因可以解释这种快速的变化。首先，政府已转发的政策支持项目的私人住宅。这已经被证明是推动中国经济发展的非常重要的。其次，随着经济的发展，人们的生活水平得到了提高。他们想拥有自己的住房，以满足他们的需求。
这一变化使更多的人拥有更大的生活空间。同时，人们感到压力，赚更多的钱，他们可以购买自己的房子。
