Diversity and unity of ethnic economic development in China: Diversity and distribution pattern of ethnic economic development in China: Different ethnic groups and their different lifestyles are formed in different geographical and ecological environments. China has a vast territory, and its geographical and ecological environment is complex, which makes all ethnic groups growing and multiplying in this land have formed various economic and cultural characteristics since ancient times. Unity and internal relations of economic development of all ethnic groups in China: In different geographical environments, all ethnic groups have formed different lifestyles and economic types in history. Generally speaking, these economic types are divided into farming economy, animal husbandry economy and gathering and hunting economy. These economic types need communication and interaction to complement each other. Only complementarity can promote their respective economic development and enrich and improve their economic life. This complementarity determines the adsorption and dependence of different economic types of ethnic groups in China, as well as the cohesion of ethnic groups.
