Abstract: Founded in 1865, Nokia has created a brilliant record of occupying the first place in the mobile phone market for 14 consecutive years. However, such a behemoth has disappeared from the mobile phone market in just four years, and its experience is embarrassing. The rapid decline of a company must not be accidental. The failure of its company's innovation strategy is an important reason for its weakness, and Nokia's board of directors is even more responsible for the failure of its company's innovation strategy. Here, the article analyzes the reasons for the failure of strategy from the perspective of the board of directors. At the same time, it is compared with the rebirth of Nokia under the new board of directors, and the influence of the board on the company's innovation strategy is analyzed.
