Corporate governance mechanisms in the Information Technology (IT) industry are viewed as pivotal for the success of IT organizations. While corporate governance, particularly in terms of board characteristics, has been extensively studied in other disciplines, it has not received as much attention in the Information Systems discipline. This study investigates the effects of board structure and its changes (i.e., board flux) on organizational performance. Results show that board size, gender diversity, and board age have curvilinear effects while board independence has a positive effect and board flux has a negative impact on performance. However, the negative relationship between board flux and performance was weaker for firms with a higher, as compared with those with fewer, number of independent directors. In addition to making a useful contribution to the sparse literature on the role of corporate governance in IT organizations, our study has strong implications for research and practice.

信息技术（IT）行业中的公司治理机制被视为IT组织成功的关键。尽管公司治理，尤其是董事会特征方面的治理已在其他学科中进行了广泛研究，但它在信息系统学科中并未受到太多关注。这项研究调查了董事会结构及其变化（即董事会变动）对组织绩效的影响。结果表明，董事会规模，性别多样性和董事会年龄具有曲线影响，而董事会独立性则具有积极影响，董事会通量对绩效有负面影响。但是，与独立董事人数较少的公司相比，董事会绩效和绩效之间的负相关性较弱。
