与全国各兄弟台一样,河北电视台的经济节目也是上个世纪90年代初在党的工作转移到以经济建设为中心上来这一大背景下创办的。那时候几乎是一夜之间,经济电视台、经济频道、经济节目遍及大江南北。然而好景不长,由于体制和节目自身及管理等诸方面原因,经济节目渐渐
Like all fraternal Taiwan compatriots, the economic programs of Hebei TV Station were also started in the early 1990s when the party’s work shifted to centering on economic construction. At that time, almost overnight, economic and television stations, economic channels, and economic programs spread all over the country. However, the good news is not long, due to institutional and program itself and management and other reasons, economic programs gradually
