伴随经济结构调整而出现的高职院校专业调整,需要借助部分高职教师的人力资本更新来完成;教师人力资本投资的沉没成本对其人力资本更新有负面影响;政府、高职院校及教师个人应当积极采取措施,尽可能降低人力资本投资的沉没成本,减少沉没成本所引起的人力资本投资不足或投资过度现象,鼓励教师主动进行人力资本更新。 The professional adjustment of higher vocational colleges that accompanies the adjustment of economic structure needs to be completed with the update of human resources of some higher vocational teachers. The sunk cost of teachers’ human capital investment has a negative impact on the renewal of human capital. The government, higher vocational colleges and Individual teachers should take active measures to minimize the sunk cost of human capital investment and reduce the underinvestment or overinvestment of human capital caused by sunk cost and encourage teachers to take the initiative to update human capital.
