1. Usage: The office building is mainly used for offices of enterprises and institutions, providing office space for various institutions and companies. Shops are mainly used in retail business and service industry, providing places for commodity sales and services.

2. Geographical location: Office buildings are often large-scale independent buildings, located in commercial areas or office areas. Shops are often located on both sides of the street or at the bottom of the business center, which is convenient for attracting pedestrians and customers.

3. Return on investment: The return on investment of shops is often higher than that of office buildings. The total price and rent of shops are higher. Because of the development of surrounding facilities, there is more room for appreciation of commercial value, and the investment risk of shops is relatively low and the return is high.
