Private sector development and urbanization are crucial for China's economic growth. Urbanization provides opportunities for private businesses to thrive, leading to overall regional development. With more people moving from rural to urban areas, the private sector plays a key role in creating non-agricultural jobs. China's urbanization process heavily relies on the support of private businesses. The World Expo 2010 in China highlighted the importance of urbanization for a better quality of life. Understanding urbanization theories is essential for studying China's private sector growth.
