There are two labor insurance pension systems running in Taiwan at this moment in time; the labor insurance pension runs by the government, and the labor standards law pension system both old and new systems are the responsibility of the private companies. The labor insurance pension was introduced in 1950. Through the years due to the population ageing; people are living longer and having fewer children, the rapid changes of economy and etc. the original lump sum pension is no longer enough to sustain a standard of living for the worker-retirees. Moreover, the rate of the labor turnover is high for the reason that the majority of Taiwanese private companies are small to medium enterprises with the average life expectancy of around 13 years only. Therefore most of the workers who work for the private companies are not qualified to claim pensions after their retirements although they are covered by the labor standards law pension scheme. The pension provision intends to prevent poverty in old age but under this circumstance those retirees are not having their financial security in the old age and are creating social issues. To reinstate this issue, the labor insurance pension system has carried out by the government in January 2009, after a major update of the labor standards law pension system in July 2005, the method of repayment has changed from the defined benefit plan to the defined contribution plan in addition to allowing the qualifying years carry forward to the new employers when the workers change jobs. Furthermore, the pension repayment is revolutionized from a single lump sum payment to an individual retirement account system complemented by monthly repayments. All of these changes are to secure the worker-retirees financially in their old age. The objectives of this study disclose the transformations of the labor retirement insurance pension systems in Taiwan and the existing modification of the Labor Insurance Act, the benefits of the Labor Standards Act pension system along with the revised Labor Pension Act. A few important factors below have been concluded in this study after analysed the revise of pension benefits systems: First of all, the repayment has changed from a single lump sum payment to monthly repayments. Secondly, the method of repayment has changed from the defined benefit plan to the defined contribution plan. Finally is to determine who are safeguarded? The protection of the social insurance is not only for the small specific groups of people but the majority of individuals. As a result, nowadays the labor pension benefits systems in Taiwan have achieved the task of securing a standard living for the retired workers. The concept of this study is to learn the affect of the changing of the economic climate and increased life expectancy on the possible forthcoming pension¡¦s crisis followed by constructive proposals to anticipate the existing labor insurance pension systems meet the needs of the worker-retirees and achieve the objectives of sustainable management of the pension systems and maintain a secured society in Taiwan.
