This sentence was correct. Culture is a product of society, reflecting the style, characteristics, and values of society. Political economy was the foundation and pillar of society, reflecting the productivity, production relations, and wealth distribution of society. Therefore, in a certain period of time, culture is the reaction of politics and economy in a certain period of time. The two are mutually connected, influenced and interacted. For example, in the early 20th century, the rapid development of American capitalists promoted the prosperity of culture, including the development of movies, music, literature, and other fields. The prosperity of this culture was not only the embodiment of the political and economic advantages of the United States, but also the result of the needs of the capitalist economy. Similarly, in the early 20th century, China's traditional culture was influenced and impacted by Western culture, and important cultural heritages such as the New Culture Movement also appeared. Therefore, it could be said that culture was the manifestation and reflection of politics and economy. The two were inseparable.
