With a focus on China's biggest internet companies, Alibaba and Tencent, the case study describes their respective histories, fintech subsidiaries and platform-based ecosystems. It illustrates the strategy issues that arise from an institutional void and market uncertainty: how to determine the business model, generate unprecedented value for customers, and ultimately compete with foreign as well as local rivals. It aims to help students understand the opportunities and challenges for firms in emerging markets, the evolutionary nature of strategy-making, the digital transformation, how new business models give rise to new regulatory challenges, and how firms respond to changes in the institutional environment. The case has four parts. The first two describe the growth of Alibaba and its fintech subsidiary Ant Financial, and of Tencent with its superapp WeChat and fintech subsidiary WeChat Pay - noting how each built its own ecosystem and their mutual attempts to squeeze the other's core business. Part 3 describes the pre-existing banking and finance industry in China. Part 4 explores their CSR (Corporate Social Responsibility) initiatives in the face of increasing regulatory and institutional pressures.

As a result of fast-developing mobile technology, companies must deal with increasing business complexity in a high-velocity environment. The Uber vs. Didi case illustrates a wide range of strategic issues that a company may face when creating a new business model, generating unprecedented value for customers, challenging traditional business and regulatory frameworks, and expanding into an emerging market to compete with local rivals. The case is about Uber's competition with Didi, its local rival in China. The first part describes the traditional taxi industry, using the illustration of the US taxi medallion system. It explains Uber's platform-based business model, value innovation, challenge to government regulation, and surge pricing model, as well as associated ethical issues. The second part describes the emergence of Didi in China and how it challenged Uber when it entered China's ride-hailing market. Unlike its rapid expansion in the US and other countries, Uber had a bumpy ride in China. In June 2015, Didi was reported to have 80.2% of the market, outperforming Uber's meagre 11.5%. With China's internet giants joining the battle as strategic investors-Baidu (backing Uber), Alibaba and Tencent (both backing Didi), and from Silicon Valley-Apple (backing Didi), the race between Uber and Didi has far-reaching implications.

The case describes the battle between Google, the world's leading search engine, and Baidu, a local entrepreneurial firm in China. In 2009, Baidu's internet traffic share in the country was over three times that of Google and Yahoo!China. Would Google utilise its global resources to impose its dominance in China? Could Baidu defend its leading position?
