The rise of e-commerce in Asia is shaking up the logistics industry. The Asia-Pacific region is now the world's largest market for online shopping. The global economy may be slowing, but faster Internet connections and the spread of mobile phones translate to more growth for online sellers. These days, it is how the goods are delivered as much as the goods themselves that separates the winners from the losers. Often, the "last mile" presents the biggest hurdles. To clear those obstacles and gain an edge, companies are pursuing acquisitions and innovative partnerships.
