Xian generally has higher housing prices compared to Lanzhou. This is primarily due to several factors, including economic growth, population density, and infrastructure development.

Xian, as a historical city with significant cultural and tourism value, has seen substantial economic growth over the years. This has attracted a large number of people seeking employment opportunities, leading to increased demand for housing. Additionally, Xian's infrastructure, including transportation and public services, has been improving, making it an attractive destination for both locals and expatriates. According to data from the National Bureau of Statistics of China, the average housing price in Xian was approximately 10,000 yuan per square meter in 2021, while in Lanzhou, it was around 8,000 yuan per square meter during the same period.

Lanzhou, on the other hand, is the capital of Gansu Province and has a lower population density compared to Xian. This lower population density contributes to a more balanced housing market, with less intense competition for housing. Moreover, Lanzhou's economic growth has been slower than that of Xian, which has resulted in a more stable and less expensive housing market. However, it is important to note that Lanzhou's housing prices have been increasing in recent years, reflecting the broader trend of rising housing costs across China.

Another factor contributing to the higher housing prices in Xian is its status as a major transportation hub. Xian is located at the intersection of the Silk Road Economic Belt and the Yangtze River Economic Belt, making it a strategic location for trade and commerce. This has led to increased investment in the city, further driving up housing prices. In contrast, Lanzhou's economic activities are more centered around agriculture and traditional industries, which have not experienced the same level of growth as Xian's modern sectors.

In conclusion, Xian generally has higher housing prices compared to Lanzhou due to factors such as economic growth, population density, and infrastructure development. While Lanzhou has seen some growth in housing prices, it remains a more affordable option for those looking to purchase property in the region.
