当前协作配送模式未达到碳排放最优状态，低碳额外支出成本及碳数据核查难题导致物流配送企业减排动力不足，如何激励协作配送企业采用低碳模式对实现双碳目标至关重要。本文依托政府主导的数字化平台，设计双重低碳激励策略鼓励企业采用协作配送低碳模式。首先，构建利益损失和碳排放量化模型，计算协作配送低碳模式与传统模式的成本和碳排放差值；其次，提出考虑碳交易收益和政府补贴的双重激励策略，设计基于减排贡献的碳配额机制和双重激励流程，对比分析单一激励和双重激励策略对企业和政府最优决策的影响；最后，通过数值实验对模型和策略的有效性和可行性进行检验。结果表明，依托数字化平台的协作配送低碳模式相比于传统模式减少了31%~67%的碳排放量；基于减排贡献的碳配额机制能够提高企业采用协作配送低碳模式的意愿；双重低碳激励策略能够降低15%~31%的政府财政支出，碳排放超额惩罚机制能够约束高排放企业。以上结论可为政府分配物流配送领域碳配额、实施低碳激励和超额惩罚提供参考。

If collaborative distribution is optimized in a low-carbon model as opposed to a low-cost model， the cost and carbon emissions will be different. Distribution companies lack motivation to reduce emissions due to higher low carbon expenditure prices and difficulties with carbon data verification. Enterprise alliances seeking to maximize economic benefits typically opt for the low-cost model， so collaborative distribution model has not yet achieved the state of minimizing carbon emissions currently. How to precisely incentivize collaborative distribution companies to adopt the low-carbon model is crucial to achieving the dual-carbon goal.A dual low-carbon incentive strategy is created based on information collected from a government-led digital platform to encourage distribution companies to adopt the low-carbon model. Firstly， adopting incentive strategies requires a scientific estimate of the benefit loss and carbon emission of the alliance members. This problem is modelled as an integer programming which minimizes vehicle routing costs or carbon emissions for sub-alliances， and then costs and carbon emissions are calculated. The cost-sharing values and carbon emissions of each participant in the two models are determined using the Shapley value method and benefit loss models and carbon emission models are created using these data. Secondly， distribution companies are only encouraged to adopt the low-carbon model when the benefit loss is fully made up for. Based on this， a dual low-carbon incentive strategy is suggested considering government subsidies and revenue from carbon quota trading， a carbon quota mechanism is designed based on emission reduction contribution， and compares and the impact of a single incentive strategy and a dual incentive strategy on the best choice made by companies and the government is analyzed. Finally， numerical experiments are used to determine whether the model and strategy are valid and workable.Results indicate that compared to the conventional model， the collaborative distribution low-carbon model based on the digital platform reduces carbon emissions by 31% to 67%. Distribution companies may be more inclined to adopt a low-carbon model if carbon quota mechanisms are based on emission reduction contributions. The dual low-carbon incentive strategy can reduce government fiscal outlay by 15% to 31%， and the carbon emissions overrun penalty mechanism can penalize high-emitting enterprises. The government can use this study as a supplement to current theory and practice to distribute carbon quotas for distribution companies， implement low-carbon incentives， impose penalties for exceeding them， and assist in meeting the double carbon target on schedule.
