中文摘要
鑑於現實社會中,廠商擁有龐大連鎖銷售網絡的現象已成為一種常態,本文探討擁有多銷售據點的廠商,在獨占以及由獨占開放為雙占市場的兩種情況下,廠商旗下便利商店的區位分析,並得出了以下的結論:(1)獨占的連鎖便利商店廠商會同時調整分店的規模與控制分店的家數,以獲取最大的總利潤。(2)新進廠商不會選擇與既存廠商的所有分店同址競爭,因為此時兩家廠商都不存在正的利潤。(3)在短期時,新進廠商會選擇與既存廠商異址競爭,且無論新進廠商是否在頭尾兩端的零星市場設分店,都存在Nash均衡解。(4)在長期時,既存廠商不但可以變動分店規模的大小,同時也可以改變分店的位置來與新進廠商競爭,最後結果為兩家廠商皆會達到Nash均衡解。(5)根據數值模擬分析的結果可知,當獨占開放為雙占市場時,由於增加競爭的緣故,會使得消費者剩餘增加,有助於社會福利的改善。

Abstract
In view of the fact that multi-store firms have been normal in a real society, this paper is concerned with the spatial decision of a multi-store firm under price regulation. It is shown that a multi-store firm with monopoly power will select as decision variables the size of a single store and the number of stores at the same time. In the duopolistic market, the new entrant will not compete with all stores of the incumbent on the same location, because of the non-existence of positive profit for both firms in this case. The new entrant will select to locate differently to compete with the incumbent in the short term. It is shown that there exists a Nash equilibrium regardless of whether or not the new entrant sets up its stores in the two ends of the linear market area. However, in the long run, the incumbent will decide not only the size of the stores, but also the locations. Nash equilibrium is shown to exist also in the long run. Finally, some numerical simulations of price regulation on welfare are carried out in the last section.

Keywords:location, multi-store firm, price competition
