　　There is no cause-fect relationship between the cultural diversity，the number of ethnic groups of which an independent nation or region with sovereignty consists ，and the economic development within the nation or region in a certain period of time. For one thing, the cultural diversity exerts no influence on such agricultural activities as farming, fishing, and domesticating. History has demonstrated that the crop yields and quality are independent upon the number of ethnic groups. For another, the development of industry is also not closely associated with the cultural diversity.

　　China is a typical example. Although this country has exactly 56 ethnic groups, the industry lags behind Japan whose ethnic composition is rather homogeneous.

　　In terms of education, the cultural diversity plays less important roles. Public schools might have excellent faculties and facilities whatever the cultural diversity conditions. Tsinghua University in China serves as a good example. In this university, ninety percent of students are Chinese in nationality. Another example is BLCU where 45% students are of international backgrounds. This university still develops fast. Private schools also disconnected with cultural diversity. MIT, Harvard, Stanford, Princeton, and Yale all are distinguished private universities that welcome international students with distinct culture, religion, and even race.

　　To sum up, the cultural diversity has little to do with the country. That is to say, the economic development and education are independent upon this concern.

　　It is the cultural diversity that exerts considerable influences on the development of a nation in such fields as economy, education, and technology. In the arena of economy, the cultural diversity forces a government to take very prudent measures to tackle the problems concerning energy and resource because different ethnic groups might have conflict interest. Naturally, the government might have to consider environment and other aspects, resulting in the sustainable development. A convincing example is the U.S economic development that saw in 1960’s the recession due to the discrimination against the color people especially the black people or Afro-Americans. On the stage of education and technology, it is almost self-evident that the larger the number of cultures in a human community, the heavier the competition and the faster the speed of development will become.

　　Admittedly, it is once believed that the cultural diversity hinders rather than helps a nation to develop. The main reason of this argument is that many ethnic groups are vulnerable to racial conflicts. But this clearly goes against the facts and figures. The conflicts are not rooted in the ethnic diversity. Within an ethnically homogeneous nation, the conflicts are yet frequent. Those who hold negative attitude towards ethnic diversity are suggested to study the human conflicts with insights.

　　To sum up, it is benicial for a nation to have a variety of distinct ethnic groups.
