目前全国省市级电视台中,已有20多家电视台开办了科教频道,主要是因为无线台和有线台合并以后,频道资源相对增多和观众需求的结果。科教频道的发展要依托于大的环境背景,首先是知识经济时代的到来,还有国家一直在大力提倡科教兴国和科技创新。全国范围内涌现出一批科教频道,纷纷得到了当地各级领导和观众朋友们的热情支持,但是,也存在着发展不平衡的问题。 At present, more than 20 television stations in China have set up science and education channels in China’s provincial and municipal TV stations mainly because of the relative increase in channel resources and audience demand after the merger of wireless stations and cable stations. The development of science and education channels should rely on a large environmental background, first of all, the advent of the era of knowledge economy, and other countries have been vigorously promoting the rejuvenation of the country through science and education and technological innovation. A number of science and education channels have emerged throughout the country and have received the enthusiastic support of local leaders at all levels and audience friends. However, there are also unbalanced development issues.
