Online channel strategies under different offline channel power structures for the Belt and Road of China

ABSTRACT

This paper explores the online channel strategies adopted by Chinese manufacturers with regard to the Belt and Road. It also investigates the effect of offline channel power structures and maritime transportation costs on online channel mode selection and pricing strategies. The offline channel power structures are classified into three types, namely, Chinese manufacturer Stackelberg (MS) structure, vertical Nash (VN) structure, and foreign retailer Stackelberg (RS) structure. Furthermore, a game model is developed among the Chinese manufacturer, foreign retailer, and cross-border e-tailer to investigate the interactions among offline channel power structures, maritime transportation costs, and Chinese manufacturers’ online channel mode selection. The results show that Chinese manufacturers’ preferences for the online agency selling mode increases correspondingly with the decrease in their market position and bargaining power. Moreover, foreign retailers can obtain higher profits in the online agency selling mode under the VN structure. However, the level of profit for foreign retailers depends on the intensity of their competition with cross-border e-tailers under the MS and RS structures. Finally, consumers in countries along the Belt and Road can obtain a higher surplus in the online agency selling mode under all of the structures.

孕妇外周血PCR技术用于胎儿产前性别诊断的可靠性分析

采用多聚酶链反应（ＰＣＲ）技术，以Ｙ染色体特异重复序列Ｙ１．１、Ｙ１．２和ＳＲＹ基因编码区Ｐ１、Ｐ２为引物，分析了用孕妇外周血进行胎儿性别诊断的可靠性，并与绒毛样本进行了对比。结果表明：用孕妇外周血时，Ｙ１．１，Ｙ１．２引物的诊断符合率为７５％；Ｐ１、Ｐ２引物不能扩增出Ｙ特异ＤＮＡ序列。而用绒毛样本时，两种引物的诊断符合率均为１００％。结果提示：孕妇外周血ＰＣＲ技术用于胎儿性别诊断尚有待改进，而采用绒毛样本进行胎儿性别诊断更为可靠。     

Japanese perspective of driver information systems

A perspective view of of Japanese R&D activities of Driver Information Systems is given from the standpoint of developing joint projects by public and private sectors. First, a brief history of the R&D activities is illustrated from above mentioned standpoint. Then, two major projects, AMTICS and RACS, and the social backgrounds of these projects are explained. In order to give a clear idea of both projects some technical details are treated.Based on the history and the present status of the developments, the basic design conceptions of Japanese Driver Information Systems are explained and several factors or reasons which have influenced to the design conception are discussed. Then, the promoting systems of the R&D activities are generally explained and present status of the projects and future problems in developing more advanced systems are also handled. A brief discussion on the establishment of international standard is also mentioned as a final comment.
