物流产业集聚对碳排放跨区域转移的作用机制

基于2002~2015年中国多区域投入产出表（MRIO）数据，结合中介效应和动态门槛效应模型，检验物流产业集聚对物流业碳转移的影响机制，并拓展性地就物流产业集聚对物流业碳转移方向的非对称性影响进行研究.结果表明：物流产业集聚与碳转移之间呈显著的正向关系.物流产业集聚不仅直接促进碳转移，还通过信息化运作和交通运输压力作用于物流业碳转移.信息化运作约束下，物流产业集聚对物流业碳转移的影响总体呈倒U字型特征；交通运输压力作用下，物流产业集聚对物流业碳转移的影响呈梯度式增强特征.物流产业集聚对物流业碳转移的影响在方向上具有非对称性特征.

The action mechanism of logistics agglomeration on the cross-regional transfer of carbon emissions

Based on the data of China's multi-regional input-output table (MRIO) from 2002 to 2015, a series of empirical studies on the action mechanism of logistics agglomeration on cross-regional carbon emission transfer were conducted by means of mediating effect model and panel threshold model. Then, the asymmetry of the impact of logistics agglomeration on the logistics carbon transfer was demonstrated. Findings indicated that logistics agglomeration significantly promoted the logistics carbon transfer. The information operation weakened the positive effect of logistics agglomeration on carbon transfer, and the transportation pressure strengthened the promotion of logistics agglomeration on the carbon transfer. Under the constraints of the information operation, the influence of logistics agglomeration on carbon transfer was generally in an inverted U-shaped curve. Under the pressure of transportation, the influence of logistics agglomeration on carbon transfer showed a gradient enhancement. Meanwhile, the influence of logistics agglomeration on carbon transfer was asymmetry in direction.
