Abstract

In 2020, the number of shared bike users has reached 253 million in China, covering more than 360 cities. What is more, the number of shared bikes has also ascended to 240,000 in Shenyang, with a peak average number of daily trips arriving at 2 million. It is obvious that shared bikes have become an important part of trip modes among individuals. However, people's awareness of getting around is different from that in the economically developed area because of the long and cold winter, relatively small population, and slow economic growth in Northeast China. This research analyzed the use and distribution features of shared bikes in Shenyang as well as evaluating its carbon reduction effect with a combination of life cycle assessment (LCA), questionnaire survey and web crawler. The results showed that the proportion of shared-bike trips within the second ring road of Shenyang was as high as 69.4\%; the willingness of the winter population to use shared bikes decreased by about 75\% compared with other seasons; approximately 1/3 of the public did not report any damage to shared bikes; it is predicted that the amount of per-capita carbon saving would have risen from 22.75g/km to 51.17g/km if the replacement ration of the shared bike to cars and taxis increases by 10\% each. Besides, the amount of per-capita carbon saving would have dropped from 22.75g/km to 15.41 g/km if the replacement ratio of the shared bike to cars and taxis falls by 50\%.
