In this paper，we adopted the big-data-aided content analysis approach and Boyi DiVoMiner ^® platform for analyzing the reports of public bicycle in the four places（Mainland China，Hong Kong，Macau，Taiwan）across straits. This paper tried to explore and compare the focus and governance issues of public bicycle services in various media，in order to understand the public services and management issues involved in the use of public bicycle. Overall trends in the reporting volume show that public bicycle/bicycle sharing has become a hot topic，especially in mainland China. The mainland China is dominated by private investment，such as Mobike and OFO，while Taiwan region develops by the government represented by YouBike. In terms of its advantages，the mainland China attaches great importance to its convenience，and Taiwan cares about environmental protection or green travel. The bicycle management and maintenance problem is the biggest governance difficulty，and the development of management standards and policies is the most demanding improvement measures. This study attempts to provide operational strategies for public transport services in public services，and a scientific reference for public services in government governance and enhancing credibility.
