What is the appreciation potential of subway stations?

Taking the site as the center, one kilometer is the most effective radiation radius. The closer to the site, the higher the value, but the price will not be much different. But one kilometer away, the value is greatly reduced. However, compared with the influence of subway on the property in the main city, the property appreciation potential in the sub-center area is greater. For example, the average price of real estate in the main city is now 1 more than ten thousand, and the price near the subway entrance may be one or two thousand yuan higher. However, remote areas are likely to rise to the level of the main city because of the opening of several subways in the future, and the increase will be very large, so remote areas are more affected by subways. There is a concept of "time for space". The distance from the remote area to the main city is calculated by the arrival time of the subway, not by the actual distance, thus enhancing the value of this area. "
