The Impact of China's Transportation Industry Development on GDP

The transportation industry is the most basic of many economic industries in China, but it plays an irreplaceable role in the development of our economy. As an important part of the national economy, China's transportation industry has great influence on the economic development of the country. This paper analyzes the relationship between the transportation industry and GDP, studies the contribution of the transportation industry to GDP and the impact mechanism of the development of the transportation industry on GDP growth, and systematically analyzes the development status quo, characteristics, problems and countermeasures of China's transportation industry by using literature analysis, data collection, empirical analysis and problem research methods. The empirical method used in this paper is co-integration analysis method. Through this method, it is concluded that highway mileage, inland waterway mileage and regular flight route mileage have no significant impact on China's GDP, while railway operating mileage, oil (gas) pipeline mileage and cargo throughput of coastal ports have significant impact on China's GDP. China's GDP will increase by 81,383.5 billion yuan; Every 1% increase in the mileage of oil and gas pipelines will reduce China's GDP by 27,851.4 billion yuan; For every 10,000 tons increase in cargo throughput at coastal ports, China's GDP will increase by 0.934126 million yuan. This paper aims to provide scientific basis for the study on the relationship between the development of China's transportation industry and GDP, and provide theoretical and practical support for promoting the sustainable development of the transportation industry and promoting China's economic growth.
