绿色供应链的政府激励机制研究：惩罚还是奖励

基于绿色供应链协调的特点阐述了政府对绿色供应链协调实施激励的必要性。基于相关研究提出三个假设并构建政府对绿色供应链协调的激励模型以验证假设。结果证明了政府针对节点企业的绿色产出提供线性激励的必要性，否定了针对单一企业绿色产出未达政府标准而给以惩罚的有效性。在努力程度为特定分布的情况下各节点企业受到政府惩罚的概率与绿色供应链整体产出无关；节点企业相互独立的努力水平之加总与绿色供应链整体产出同向变化。

Governmental Incentive Mechanism of Green Supply Chain Performance： Punishments or Rewards

This essay expounds on the necessity of governmental incentive mechanism implemented in GSC （green supply chain）, according to the characteristics of GSC coordination. Models of governmental incentive mechanism have been constructed here to inspect three hypotheses generated by related researches, and the results are as follows： first, linear incentive is necessary for the green output of node companies; second, punishments on companies whose single green output fails to reach government standard are invalid in effect; third, the probability of punishments on node companies is basically irrelevant to the total GSC output under particular distribution of individual efforts; and finally, the totaling of efforts from mutually independent node companies goes in the same direction with that of GSC output.
