Abstract: With the example of NVC Lighting Technology Corporation, this thesis examines the influences of institutional investors’ activism on venture shareholder’s control rights and corporate governance. This research reveals that constantly dispersed shareholding structure and increasingly powerful institutional investors will become normal in China. Whether institutions as large shareholders will improve corporate governance depends in part on their objectives, their preference and cost-revenue tradeoff. In the long term, institutional investors’ activism will promote corporation governance, and help to improve venture shareholders’ financial abilities and risk prevention abilities, and will contribute to a mature professional managers market and more powerful protection of stakeholders’ interests.
