Optimal discounts in green public procurement
通过拍卖理论分析绿色公共采购作为优惠计划如何激励企业投资绿色技术，并证明该机制能同时实现最低采购价格与绿色投资目标。
We provide an auction-theoretical analysis of Green Public Procurement (GPP) as a preferential program aimed at stimulating investment in green technologies. We find that GPP incentivizes more competitive firms to invest. We also show that GPP can be an optimal mechanism for a procurer who cares about minimizing the purchasing price while triggering green investment.
