Abstract

This paper is an attempt to investigate the non-stationary process in the global market shares of automotive industry of top 26 automotive producing nations. The time series data of global automotive market shares of top 26 automotive producing nations were collected from data stream Eikon for the period from 2002 to 2014. Augmented Dickey Fuller Unit root test (ADF URT) is used to investigate the non-stationarities or shocks in the outlined series of global automotive market shares. Findings confirmed the presence of shocks or non-stationarity (absence of stationary process) in global market shares of almost all top automotive producing nations except of Australia, India, Malaysia and South Africa for2002 to 2014. Findings further revealed that the non-stationarities got fixed at 2nd difference in all outlined series of global market shares of automotive for the period from 2002 to 2014. It is also revealed that there are the same shocking patterns in the global market shares of all top automotive producing nations with few exception.
