Let me answer your paper. There is a very close relationship between traffic development and social change. The traffic development in a certain area in a certain period must be the symbol of social production and life in this area at that time. From the perspective of the relationship between modern traffic development and social changes, this paper systematically investigates the process of traffic development from the Reform Movement of 1898 to the founding of People's Republic of China (PRC) and its interactive relationship with social changes. The article is divided into four parts: The first part introduces the traditional modes of transportation from the aspects of waterway and land, and objectively evaluates the position and function of the traditional modes of transportation. The second part deeply analyzes the motivation of the rise and development of modern transportation: economic motivation is the most fundamental driving force to promote the development of modern transportation; Political motivation not only promotes the development of transportation, but also has some negative effects. The third part introduces the rise and development process of modern shipping, railway and highway respectively. And the development of each stage. It summarizes the historical trend that modern transportation gradually replaces traditional transportation. The fourth part analyzes the extensive influence of traffic progress on modern social change from four aspects: economic change, political change, social life change and ideological change, and demonstrates the great impetus of traffic development in the process of transformation from traditional society to modern society. The article holds that the development of modern transportation is mostly based on economic and political purposes. However, the impact of traffic progress is different from or beyond people's initial expectations, covering many fields such as economy, politics, social life, ideas and so on. Therefore, transportation development must focus on its overall effect on social change, so as to better promote social progress.
