The dimensions of organization climate and the relationship between organizational climate and organizational performance were examined in 220 mangers from 44 regional hospitals in Taiwan area. This study collected data using questionnaire which measured the hospital climate and performance. In terms of hospital climate, the items from Litwin and Stringer climate questionnaire (1968) were modified to adapt the hospital environment in Taiwan. The performance measurement included patient's satisfaction and employee's satisfaction. Our experimental survey revealed that the dimensions of organizational climate in Taiwan regional hospitals consisted of "warmth and consideration", "communication and coordination", "performance standard", "work pressure" and "conflict". And, the correlation was significant between the dimension of "warmth and consideration" and "patient's satisfaction" (P<0.01), "communication and coordination" (P<0.01) as well as "performance standard" (P<0.05) and "employee's satisfaction" respectively. We also found that the dimension of "conflict" in the public setting was significantly different from the one in the private (p<0.05). however, the public and private settings were not significantly different to the dimensions of "warmth and consideration", "communication and coordination", "performance standard", and "work pressure". Furthermore, "patient's satisfaction" and "employee's satisfaction" of public setting were not significantly different from those of private setting, too. Finally, higher "employee's satisfaction" and "patient's satisfaction" associated with better organizational climate.
