Subsidy Ceilings and Sequential Synergy: Steering Sustainable Outcomes Through Dynamic Thresholds in China’s Urban Renewal Tripartite Game
Abstract
1. Introduction
- Above what critical levels do financial subsidies lead to a deterioration of cooperation? Do these critical levels show different stability for different types of subjects (e.g., developers vs. residents)?
- What quantitative thresholds cause a shift from conflict to collaboration in multi-party relationships?

5.4. Robustness Test of Critical Thresholds
- Developer Subsidy Threshold (M1): The critical value for M1 demonstrated high robustness. Its estimates remained tightly clustered within a narrow range of [575 k RMB, 625 k RMB] around the baseline value of 600 k RMB. This indicates that the fiscal limit for developer subsidies is a stable and reliable feature of the model, relatively insensitive to uncertainties in other inputs.
- Resident Subsidy Threshold (M2): In contrast, the critical value for M2 exhibited low robustness and high sensitivity. Under parameter perturbation, its estimates varied widely across a range of approximately [550 k RMB, 850 k RMB]. This suggests that the precise monetary incentive required to secure resident participation is not a fixed point but is highly contingent on the specific configuration of socio-economic factors and individual perceptions captured by other model parameters.

6.2. Balancing Nonlinear Policy Effects and Fiscal Sustainability in Community Renewal
6.3. Stage-Sensitive Policy Adjustment for Long-Term Sustainability
- For Chinese cities: Implement phase-sensitive interventions (e.g., FAR incentives during the factor-integration stage) to avoid fiscal overload. Chinese policymakers should shift toward stage-adjusted strategies: In the resource-oriented phase, the government should lead the trust framework (e.g., transparent cost–benefit demonstration platforms) rather than relying solely on large-scale subsidies. In the factor integration phase, the focus should shift to market-driven mechanisms, such as incentives for increased volume (R3), without exhausting fiscal resources. In the shared governance phase, participatory budgeting becomes viable—introducing resident involvement earlier increases transaction costs (C3↑) and destabilizes initial collaboration. This systematic advancement counters China’s one-size-fits-all participatory empowerment, criticized by Haoyu & Tao [10].
- For Global South contexts (e.g., Lagos, Jakarta, Indonesia), embed subsidy caps (e.g., M1 ≤ 0.1% × local GDP per capita) into renewal statutes. In Jakarta’s Kampung Improvement Program, studies suggest that subsidy thresholds aligned with fiscal capacity may help reduce fiscal pressure while maintaining relatively high levels of resident participation [31,55,56,57]. It should be stressed that available data on cost per dwelling, GHG reduction, and resident satisfaction remain fragmented and inconsistent, so these cases are presented here as qualitative illustrations, not as strict quantitative validations. Globally, this study offers principles to address socio-institutional tensions:
- Fiscal policy should supersede short-term political demands: Adjust subsidies to local capacity (e.g., M1 ≤ 25% of project costs).
- Active participation requires demonstrated outcomes: “Show then participate” outperforms “pay then pray”.
- Stage-by-stage analysis informs intervention timing: Track developer participation rates as key indicators for phase transition readiness.

Parameters | Simulation Data (10 k RMB) | Rationale and Description |
---|---|---|
C1 | 20 | Estimation based on the case: In the LZ renewal pilot, the government participates in infrastructure investment through guiding capital and special funds, representing approximately 20–30% of the construction cost, with the value set within the range of [30, 50]. |
C2 | 40 | At this time, the developer does not cooperate, the government needs to independently bear the renewal expenditure, according to the “full coverage” logic set higher than C1, set to [60, 80], and used for sensitivity testing. |
C3 | 10 | Referring to the special incentive ratio mentioned in the National Urban Renewal Pilot Fund Management Measures (2021), it is set at 5–10% of the total project investment, which is taken as [8, 12]. |
C4 | 30 | Based on national and local urban renewal preferential policies (e.g., tax rebates, subsidized loans, the value is set to [15, 25]. |
M1 | 15 | Based on [28] quantitative analysis of the impact of incentives on developer behavior in green building, the amount of subsidies and tax credits is set to be 15–25% of the developer’s total investment in total to motivate cooperation. |
M2 | 10 | This loss is difficult to quantify and is set to a medium–high value [30, 50] for modeling the feedback pressure on the government from policy incentive failures. |
W | 30 | Drawing on research on multi-tiered intergovernmental incentives, the central/provincial incentives were set at 5–10% of total investment at the prefecture and municipal levels, which reasonably reflects the resource feedback from higher levels on the performance of renewal projects. |
R1 | 10 | Referring to [20], the quantitative weights of the three types of indicators, namely, “environmental improvement, public service, and governance capacity”, are used in the performance assessment of urban resilience regeneration. |
R2 | 15 | Based on the marginal benefits from housing improvements, environmental enhancements, etc., in Lin and Park [31,49], set up and measure the elasticity of their impacts in a sensitivity analysis. |
R3 | 45 | Based on ROI assumptions, estimated at a reasonable profit range of 15–30 percent. |
R4 | 50 | Same as R1 |
R5 | 15 | Based on Jiayu and Xiaodong et al.’s “conservative profit” setting in the green development game model [50]. |
S1 | 30 | Lacking a direct quantitative basis, this paper estimates the cost of negative events in an old district project in Wuhan by [10,51]. |
