1983年，畫家洪平濤為提供中青藝術家發表的園地，以經營者、推廣者的角度創辦了敦煌藝術中心，走過臺灣經濟發展的八十年代，文化多元鼎盛的九十年代。除了致力於藝術產業經營外，並開辦敦煌學苑，首創民間藝術研究及欣賞的講座，開創藝術流行風潮，並出版敦煌藝訊，開設藝術網路拍賣。同時以美術史的眼光整理中國油畫史、當代水墨史，重新發掘湮沒於時代變動中傑出的藝術家。 經過敦煌引介而活躍亞洲藝術市場的老一代畫家包括余本、沙耆、李青萍、胡善餘、賈又福等…，使其在美術史、在學術上獲得應有的地位與評價。 在當代水墨書寫方面也包括張大千、江兆申、周澄、李義弘、李安成、劉國松、楚歌、蔣勳、席慕容、李蕭錕、小魚等…。
近40年藝術市場經營經驗 ，深知不同文化差異與藝術市場性格及特質，拉近了國際間文化人的距離。 經營迄今收穫多年藝術市場經驗，期望能持續將台灣本土優秀藝術家推向國際，在藝術領域中能夠發揮東方文化與世界的互動

In 1983, painter Mr. Pin Tao HONG founded Cave Art Center from the perspective of an operator and promoter in order to provide a venue for young and middle-aged artists to express themselves. It has gone through the 1980s when Taiwan's economy developed and the 1990s when cultural diversity flourished. In addition to being dedicated to the management of the art industry, it also opened the Dunhuang Academy, initiated the first lectures on folk art research and appreciation, created a popular art trend, published Dunhuang Art News, and launched an online art auction. At the same time, we organize the history of Chinese oil painting and contemporary ink painting from the perspective of art history, and rediscover outstanding artists who were buried in the turmoil of the times. The older generation of painters introduced by Dunhuang and active in the Asian art market include Yu Ben, Sha Qi, Li Qingping, Hu Shanyu, Jia Youfu, etc., which have earned them their due status and evaluation in art history and academic circles. Contemporary ink writing also includes Zhang Daqian, Jiang Zhaoshen, Zhou Cheng, Li Yihong, Li Ancheng, Liu Guosong, Chu Ge, Jiang Xun, Xi Murong, Li Xiaokun, Xiao Yu, etc. With nearly 40 years of experience in art market management, he is well aware of the differences between different cultures and the personalities and characteristics of the art market, which has shortened the distance between international cultural people. Having gained many years of experience in the art market since its operation, we hope to continue to promote Taiwan's outstanding local artists internationally and exert the interaction and influence of Eastern culture and the world in the art field.
