In Taiwan, the elder population had developed as the aging society index since September 1993 and the aging population is a stark public policy problem. The aging population need great amount of medical service and social welfare, moreover, it take a big strike to family values. In traditional Chinese society, that?s family?s responsibility to take care of elders, but the function became more weak in virtue of family structure variation. In the period of 1999 to 2003, the long-term care facilities had a large surplus of service while the market had great demand. However, we can?t find any research to discuss the real reasons about the market failure. This research base on the Theory of Planned Behavior (TPB) view to identify the motive of decision makers who might let their elder familiar go to long-term care facilities. According to the theory, three main dimensions are attitude toward the behavior, subjective norms and perceived behavioral control. We follow the main dimensions to develop the factors. As research results show that ?avoid disadvantageous rumor? and ?maintain proper family function? could explain the attitude dimension; ?obey authority? and ?relatives and friends support? might interpret the norm dimension; ?cognition about control force of environment? would elucidate the control dimension. The degree from strong to week is following as ?avoid disadvantageous rumor?, ?control force?, ?maintain proper family function?, ?obey authority? and ?relatives and friends support?. All dimensions will relative to environment, economic, age, and social position etc. This research accomplished under the caregivers who feel detrimental about social welfare and social support. The research outcomes might be different if the detrimental factors could be eliminated from caregivers. It will be a great challenge in the future for government and long-term care facilities to accommodate each other while their policy and operation spirit isn?t the same.
