Central to the financing model employed by these local governments is the exploitation of land as a resource through dual channels: land-based fiscal revenue and land-based investment. Commercial and residential lands are monetized to generate substantial fiscal income, while industrial lands are often provided at subsidized rates to stimulate economic activity. This bifurcated strategy has given rise to a land-centered wealth accumulation paradigm, where the state’s monopoly over land supply creates powerful incentives and pronounced leverage effects that translate into unprecedented fiscal and financial gains. However, this model inherently ties urban growth to land transactions and financial mechanisms, such as urban investment bonds and bank loans issued by Local Government Financing Vehicles (LGFVs), thereby embedding land deeply in the financial apparatus of urban development.

The consequences of this land-centric development strategy extend beyond pure economics; they reverberate powerfully in environmental domains, particularly in carbon dioxide emissions. Urbanization inevitably spurs an increase in construction activity, transportation demand, and a significant encroachment upon ecological land, collectively intensifying CO₂ emissions. The study reveals how the competition among regions to emulate successful growth trajectories exacerbates this phenomenon, as cities tend to converge towards land supply strategies that prioritize rapid development even at the cost of environmental sustainability. The spatial spillover effects of these strategies highlight an alarming dynamic: land-based fiscal revenue, in particular, has a pronounced spillover effect, amplifying carbon emissions not only locally but also in adjacent areas, presenting a formidable regional coordination challenge.

The nuance between fiscal revenue from land and land-based investment is critical. While land-based fiscal revenues show a clear and robust connection to heightened carbon emissions in neighboring cities, the relationship between land-based investments and emissions is more intricate and varies significantly across regions. This variation reflects the complexity of policy interventions and the heterogeneity of economic landscapes, particularly evident in China’s western and less-developed cities. These regions tend to grapple with underdeveloped financial infrastructures, necessitating stronger low-carbon land supply policies to mitigate their disproportionate environmental impact. The financial distortions created by current land policies further complicate efforts to align land use with green transition ambitions, underscoring the pressing need to rethink the symbiosis between land governance and financial market development.

Notwithstanding these challenges, Chinese local authorities have not remained passive in addressing the environmental ramifications of their land supply strategies. Initiatives promoting the “ecological redline,” efforts towards constructing low-carbon cities, constraints on construction land supply, preserving ecologically sensitive areas, and comprehensive territorial spatial planning signify proactive steps towards sustainable land management. However, the study emphasizes that the prevailing “seeking development with land” model continues to potentiate CO₂ emissions, highlighting a tension between economic imperatives and climate goals. This underscores a crucial inflection point in China’s urban development trajectory, where innovative paradigms for land allocation must be forged under stringent carbon emission constraints to harmonize growth with ecological stewardship.

A pivotal insight from this study lies in the revelation that land-based fiscal revenue is more strongly associated with increased carbon emissions compared to land-based investment. This nuanced differentiation challenges prevailing assumptions about land’s role in urban sustainability and signals policymakers to scrutinize the underlying fiscal incentives that drive land transactions. Moreover, it suggests that traditional environmental regulatory frameworks may be weakening in their efficacy to curb carbon emissions within the context of land market dynamics. The insights from this research carry profound implications, providing a foundation for crafting scientifically informed land supply strategies that reconcile economic development with low-carbon urban futures.

The findings urge a strategic readjustment of the land supply structure towards industries characterized by low carbon footprints, high technology content, and heightened efficiency. Such a reorientation can pivot China’s land market towards sustainable development pathways, turning land use into a lever for climate-friendly growth. Additionally, the study advocates for a recalibration of local government performance metrics, emphasizing the integration of environmental quality assessment into promotion and evaluation criteria. By elevating the importance of low-carbon objectives within the bureaucratic reward system, local authorities could be dissuaded from channeling land resources indiscriminately towards high-energy-consuming enterprises, thereby aligning economic incentives with ecological responsibility.

The recent reform whereby the Ministry of Finance in China assumes direct control over land transfer fee collection marks a significant institutional shift. This policy indicates a decisive move away from the entrenched practice of local governments monetizing land transfers to fund rapid expansion, hinting at an impending transformation in land fiscal policies. The implications are manifold: local governments may need to extricate themselves from the “land for development” model, necessitating alternative fiscal strategies that decouple growth from carbon-intensive land transactions. Such reforms, while rife with challenges, also open a critical window of opportunity for embedding low-carbon principles into the architecture of urban land governance.

From the natural resource management perspective, regulating land transfers with an explicit goal of carbon emission reduction emerges as a powerful instrument in China’s broader climate strategy. Achieving carbon neutrality, however, transcends land use policies alone and demands a concerted, multifaceted approach. Market-based mechanisms like carbon taxes and emissions trading systems, energy sector restructuring, industrial upgrading, and breakthrough technologies such as carbon capture and storage (CCS) coalesce to form the backbone of this endeavor. The study’s elucidation of land’s central role in urban fiscal strategies enriches this mosaic, suggesting that comprehensive climate solutions must integrate land policy reforms as a core component to be effective.

Looking ahead, the study invites further inquiry into the potential efficacy of land marketization in resolving misallocations created by government-directed land distributions. The over-allocation of residential land juxtaposed with significant population declines in certain urban areas opens questions about urban land dynamics, demographic shifts, and sustainable planning practices. These unresolved issues present fertile ground for future research, which could shed light on optimizing land resources amid shifting economic and social paradigms.

In summation, the exploration of urban land supply strategies in China reveals a critical intersection of fiscal policy, urban development, and environmental sustainability. Local governments’ reliance on land as a fiscal and investment tool has propelled vast urban transformations but at the cost of intensified carbon emissions and ecological strain. Addressing this conundrum requires systemic reforms—restructuring land supply frameworks, realigning bureaucratic incentives, and implementing rigorous environmental assessments. As China strides toward its carbon neutrality commitments, this research underscores land policy’s indispensable role as both a challenge and opportunity in crafting resilient, sustainable urban futures. The path forward lies in harmonizing economic aspirations with planetary boundaries, a delicate endeavor demanding innovation, political will, and cross-sectoral collaboration.

Central to the study’s findings is the clear positive influence of SCP on improving urban livability. Livability, a multifaceted concept including environmental quality, social well-being, governance effectiveness, and economic vitality, sees measurable enhancements in pilot cities. These improvements persist robustly even when subjected to various statistical robustness checks, bolstering confidence in SCP’s role as a catalyst in urban improvement. This suggests that the integration of advanced information technologies and smart infrastructures fosters ecosystems in which residents enjoy better services, safer environments, and more efficient urban management systems.

Delving deeper, the research highlights that SCP’s effects are not homogeneous across all cities. Larger metropolitan areas, non-resource-based cities, and urban centers boasting higher human capital endowments experience more pronounced benefits. This differential impact underscores the importance of tailored policy frameworks that consider unique city characteristics. For cities rich in skilled populations and dynamic economies, smart city initiatives act as accelerators, magnifying technological synergies and governance innovations. Conversely, smaller or resource-dependent cities face distinct challenges, necessitating customized approaches that respect their specific socio-economic contexts and developmental stages.

A particularly significant insight lies in unraveling the mechanisms through which SCP enhances urban livability. Technological innovation emerges as a fundamental driver, enabling cities to harness big data analytics, artificial intelligence, cloud computing, and other cutting-edge technologies to streamline urban operations and elevate service delivery. Beyond pure technology, the transformation of government social governance systems plays a pivotal mediating role. Smart policies and governance frameworks empower local administrations to adopt data-driven decision-making, foster participatory governance, and boost resilience against urban challenges such as congestion, pollution, and social inequities.

Moreover, the spatial dynamics of SCP reveal that smart city policies do not operate in isolation but generate positive spillover effects on surrounding non-pilot cities. This spatial spillover suggests that technological breakthroughs, governance models, and industrial innovations diffuse across administrative boundaries, potentially uplifting wider urban regions. Such findings highlight the strategic importance of integrating cross-regional cooperation into smart city development agendas, facilitating knowledge sharing, resource pooling, and coordinated action to optimize the overall regional urban landscape.

From a policy perspective, these empirical revelations warrant proactive expansion and intensification of SCP initiatives. Governments should channel increased investments into comprehensive smart city infrastructures, spanning hardware, software, and data ecosystems. Establishing special funds dedicated to such projects, coupled with incentivizing private sector participation, can accelerate deployment. Importantly, broadening the application horizons for intelligent technologies—from urban safety and healthcare to education and environmental monitoring—ensures that smart city benefits permeate all dimensions of urban life and support holistic livability enhancements.

Equally crucial is the need for nuanced policy designs responsive to city heterogeneity. Urban centers with robust human capital and economies should further embed smart technologies across enterprise production, urban management, and residential services, transforming the ‘urban disease’ problems into manageable challenges. In contrast, smaller and resource-constrained cities require targeted financial support aimed at building foundational information technology infrastructure adapted to local conditions. Smart project selection in such cities must be guided by adaptability and relevance, ensuring technology adoption aligns with developmental priorities and enhances practical outcomes.

The study also emphasizes the imperative of sustaining technological innovation and refining governance structures to consolidate smart city gains. Governments are called upon to allocate preferential financial resources towards research and adoption of emergent technologies such as AI, big data platforms, and cloud services, which underpin smart urban ecosystems. Simultaneously, transforming economic development paths to prioritize technology-driven industries positions cities on a trajectory of sustainable growth. Embedding smart infrastructures comprehensively into urban management—covering transportation, energy, health, and governance systems—further elevates administrative modernization and operational efficiency.

An additional layer involves the orchestration of cross-regional collaborative governance frameworks. Given SCP’s positive spillover effects, it is paramount that diverse stakeholders—including governments, enterprises, and citizens—forge mechanisms for cooperative urban governance beyond individual municipal borders. Intergovernmental service integration, enterprise-led cross-regional economic collaborations, and empowered citizen participation through intelligent feedback platforms constitute vital pillars of a multi-actor collaborative governance paradigm. This inclusiveness not only smooths the flow of resources and information between cities but also enhances the responsiveness and precision of urban policymaking.

Despite these advances, the research acknowledges inherent limitations needing future exploration. Notably, the observed lagged effect of SCP on urban livability points to the complexity and gradual nature of urban transformations induced by smart technologies. Longer-term studies encompassing extended temporal data ranges will be essential to fully capture delayed impacts and intricacies in SCP’s developmental trajectory. Additionally, while technological innovation and social governance mediate SCP’s effects, broadening investigation into other dimensions—such as cultural shifts, environmental sustainability, and citizen engagement—could render a more holistic understanding of smart city dynamics.

Looking ahead, the fusion of advanced information technology with urban governance exemplifies a promising frontier for enhancing global urban livability. As China’s experience demonstrates, smart city initiatives possess the transformative potential not only to upgrade infrastructure and services but to fundamentally reshape socio-economic and institutional fabrics of cities. The ongoing digital revolution in urban settings redefines how cities grow, adapt, and improve the quality of life for millions. Embracing this trend with evidence-driven policies, inclusive governance, and innovative financing will be key to realizing the promise of smarter, more livable cities worldwide.

In summary, smart city pilot construction stands as a substantive driver of urban livability improvement, delivering measurable benefits through technological innovation and governance modernization. Its heterogeneous effects urge the design of flexible and contextualized policy interventions. The reinforced role of cross-regional cooperation unveils new paradigms for urban development in interconnected metropolitan regions. While challenges and knowledge gaps remain, the strides made indicate a profound shift in urban planning—where adaptive, intelligent, and citizen-centered technologies enable cities to become healthier, safer, and more prosperous habitats for the future.

The study’s comprehensive analytical framework, combined with meticulous empirical validation, offers new lenses to decode the complex mechanisms of smart city growth and urban livability enhancement. Moving beyond conceptual postulations, the research injects robust quantitative evidence supporting the scaling up of SCP initiatives. Its spatial spillover findings further enrich understanding of regional development dynamics under digital transformation pressure. These contributions echo a global urgency to rethink urban futures, making smart cities a vital domain for interdisciplinary inquiry and policymaking innovation.

In conclusion, embracing smart city technologies and governance reforms emerges as a necessary strategy for urban centers faced with mounting sustainability, resilience, and inclusivity challenges. As demonstrated by China’s quasi-natural experiment, SCP does not merely upgrade physical infrastructure but catalyzes broad systemic changes fostering improved urban quality of life. The interplay of innovation, governance, regional cooperation, and targeted policy support forms a complex yet navigable pathway toward reimagined cityscapes—where technology and society converge to create truly livable urban environments.
