Cross-Border Labour Mobility and Institutional Barriers in the Guangdong–Hong Kong–Macao Greater Bay Area

This paper provides one of the most detailed empirical examinations of labour mobility within the Greater Bay Area, focusing on why cross-border movement remains limited despite heavy policy promotion. Drawing on survey data, policy analysis and mobility statistics, the authors show that institutional frictions – not worker preferences – are the primary constraint. Key barriers include non-transferable social security systems, professional qualification recognition, immigration controls and divergent tax regimes between the mainland, Hong Kong and Macao. The study pays particular attention to young professionals and cross-border commuters, highlighting a gap between policy rhetoric on “talent circulation” and lived administrative reality. Pilot schemes in Hengqin and Qianhai are assessed as partial fixes rather than systemic solutions, often benefiting firms more than workers. The authors argue that without harmonisation of welfare entitlements and clearer legal frameworks, labour integration will remain symbolic. The paper concludes that labour mobility is the GBA’s weakest integration pillar – and a critical test of whether the region can evolve beyond infrastructure-led integration.

Innovation Integration and Regional Resilience in the Guangdong–Hong Kong–Macao Greater Bay Area

Focusing on innovation ecosystems, this paper analyses how cross-border collaboration affects regional economic resilience in the GBA. Using patent data, firm-level networks and spatial econometric modelling, the authors map innovation flows between Shenzhen, Guangzhou, Hong Kong and Macao. They find strong asymmetry: Shenzhen acts as the primary innovation hub, Hong Kong as a financial and knowledge intermediary, while Macao remains weakly embedded outside niche sectors. Policy initiatives have increased formal collaboration, but informal barriers – professional accreditation, IP enforcement differences and talent mobility – still limit spillovers. The paper stresses that resilience depends less on headline R&D spending and more on institutional permeability across borders. COVID-19 is used as a stress test, revealing that regions with diversified innovation linkages recovered faster. The authors argue that without deeper regulatory alignment, the GBA risks becoming a cluster of connected cities rather than an integrated innovation system.

One Country, Two Systems and Regional Planning: The Political Economy of the Greater Bay Area

This paper situates the GBA within China’s broader political economy, asking whether “One Country, Two Systems” can sustain long-term regional planning coherence. Through policy document analysis and elite interviews, the authors examine how central authorities balance national strategic goals with SAR autonomy. They argue that the GBA is less about economic necessity than political signalling – demonstrating integration without formal constitutional change. The study shows how planning language increasingly reframes Hong Kong and Macao as functional nodes rather than autonomous economies. However, legal divergence remains a structural constraint, particularly in land use, public finance and social policy. The paper warns that over-reliance on administrative coordination, rather than rule-based integration, may limit predictability for investors and residents. The authors conclude that the GBA is best understood as a managed integration project – stable in the short term, but institutionally fragile if policy coherence is not matched by legal clarity.
