Which concept best describes a business model that grows by attracting more participants, such as customers and merchants, leading to further expansion?

选项：

A.

A one-sided network

B.

Crowdsourcing

C.

A multi-sided network

解释：

C is correct because a multi-sided network involves various types of users, such as buyers and sellers or hosts and guests, where the addition of more users on one side attracts more users on the other. This mutual attraction facilitates the network's growth, often exponentially, as seen in platforms like credit card networks or digital marketplaces like Airbnb. The growth is fueled by the interconnectedness of different user groups, which, as they expand, enhance the network's overall value and create strong competitive barriers​​.

A is incorrect because a one-sided network benefits only one type of user, lacking the reciprocal growth mechanism of a multi-sided network.

B is incorrect as crowdsourcing involves gathering contributions from a broad user community, which is different from the growth mechanism in multi-sided networks where the interplay between different user types drives expansion.
