Test analysis: This question examines the relationship between production and consumption. According to the title, since the opening of the Beijing-Tianjin intercity train on August, 2009, the number of tour groups from Beijing to Tianjin has increased by 35% compared with that before the opening, indicating that production determines consumption and creates motivation for consumption, so view A meets the meaning of the question, view B and C are wrong, view D determines consumption, and view D is correct but does not meet the meaning of the question. The stem emphasizes the role of production.

This problem is generally difficult.
