The world is changing every minute nowadays .If one wants to keep up with the high pace of development , he or she must have a strong ability to being innovative . Being innovative is a most important quality in any field .  Politicians should be innovative when making policy , business man should be innovative when doing business , educators should be innovative when developing education plans . So , I strongly agree that In any field those in power should step down after five years.  Ten years ago ,  the most powerful household appliances industry in china was the Haier industry . At that time , it’s products were claimed the best and every family wants to have one of them . But now , we rarely hear the name Haier , it already lost it’s market to other new enterprises . There might be multiple reasons for the sinking of Haier , but the most important reason is that it’s leaders were too stiff to make changes . When other enterprises devote a lot of power to produce more smaller washing machines and more high definition televisions , Haier stick to the traditional form . The senior leaders refused to take the risk .  Eventually , Haier lost most of its engineers to other household appliances enterprises and gradually disappear from the industry . Although today Haier come back with a whole new face , but it can never be that popular like ten years ago . Because of the error of the leaders ,a strong empire was destroyed , If the leaders of Haier at that time was replaced as long as the leader refused to innovate , it might be whole new story .  When the Chairman Mao replaced by Deng xiao ping , china's economy step into a new high , the reform and opening-up policy help Chinese people walk out of poverty and feudal and embrace a new era . New leadership can inject new energy to enterprises and lead to a new high .  However , some traditional industries that have already shaping a complete industry chain need a experienced man to lead . The person who lead these kinds of industries should be very familiar with it . In this case ,it might be harmful for the industry to change leaders in a short run .  In whole , changing leaders would be better to enterprises to get to a new high and stay competitive .
