讲座内容摘要

The study examines how a manufacturer’s production economies of scale affect its   incentive to encroach on the retail market when the direct channel is   organized either centrally or through a decentralized direct-channel division. Encroachment can expand total output and lower average production   cost, but it also reallocates sales across channels and alters downstream   incentives. We show that economies of scale do not uniformly favor   encroachment; rather, their effect depends fundamentally on who controls the   direct channel. Under no encroachment and under decentralized encroachment,   stronger economies of scale always increase the manufacturer’s profit and do   not harm the retailer. Under centralized encroachment, however, stronger   economies of scale can reduce the profits of both firms by shifting volume   from the relatively efficient retail channel to the manufacturer’s more   costly direct channel. We further show that the profitability of encroachment   is asymmetric across organizational structures: centralized encroachment may  underperform no encroachment when economies of scale are strong, whereas decentralized encroachment may do so when economies of scale are weak. From   the retailer’s perspective, stronger economies of scale always reduce   retailer profit under centralized encroachment, but under decentralized encroachment they increase the likelihood that the retailer benefits from   encroachment. Finally, when the manufacturer can choose its internal structure, it prefers centralization when economies of scale are weak or the direct-selling cost is sufficiently low, and decentralization otherwise.   These findings identify organizational structure as the key mechanism through which the same upstream cost force reshapes channel outcomes.
