“…The agglomeration function of Hong Kong Zhuhai Macao Bridge is much stronger than the distribution function. Some transportation hub cities are also very important to accelerate the transfer of logistics, commerce and information flow (Lin et al, 2020), which further strengthens the promoting role of the Guangdong-Hong Kong-Macao Greater Bay Area in the development of a new development pattern of dual circulation.…”

Starting from the external circulation and internal circulation, this paper discusses the current situation, problems and countermeasures of each element of dual circulation. Although the Guangdong-Hong Kong-Macao Greater Bay Area has advantages in many aspects, there are still some problems, such as the relative unification of import and export direction, the relative concentration of product types, the imperfect supply chain, etc. In view of these problems, the paper puts forward the economic and legal measures to solve and improve, for the smooth operation of the dual circulation, security and stability to provide the basic security.

“…Most previous studies have focused on natural and ecological factors when selecting influence indicators of UGB delineation [23], [24]. For human factors, only population and transportation indicators were frequently considered, failing to fully consider the socio-economic factors related to the urban development potential, such as human activities and economic vitality [25], [26]. Residents' daily activities, such as consumption and movement, contribute to the demand for regional construction land, which can significantly shape the spatial structure of cities [27].…”

An urban growth boundary (UGB) is an important policy tool used to control urban sprawl, which can effectively balance the urban construction needs, residents' quality of life, and urban ecological protection. Current studies of UGB delineation and its indicators have paid little attention to human factors such as human activities and economic vitality, and weights for evaluation indicators have been determined highly subjectively. In response to these problems, this study integrated multi-source geographic big data to construct a total of 30 natural, human, and ecological evaluation indicators. The GIS technology and machine learning (ML) approach were combined to determine indicator weights with an officially manually drawn 2035 UGB as the reference, aiming to reduce the subjectivity. The suitability score was then calculated from indicator grading 4-1 and related weights, and high suitability (>2.15) regions were eventually delineated as the UGB. Results showed a delineated UGB of 1,528.06 km 2 with an overall accuracy of over 93% and high consistence with reference data for 2035 in the Chinese city of Changsha. The geographic big data totally contributed more than 33.72%, which mainly characterized role of human elements, and a 5-6 percentage point reduction in accuracy was found without these data. Compared with existing studies, our delineated UGB had higher accuracy and closer spatial pattern to the reference data, verifying the effectiveness and reasonability of ML-based weight setting approach and index system with geographic big data. The proposed method can provide scientific and accurate framework for UGB delineation, which can promote the territorial spatial planning and sustainable urban development.
