西方发达国家对专利制度的经济学研究已颇有深度,而我国则处于起步阶段。我国已加入WTO,面对一个竞争更为激烈、残酷的国际市场,贸易壁垒将很快由行政壁垒、关税壁垒转移到以技术壁垒为中心的非关税壁垒上来;对于在国际市场中正处于竞争弱势的我国企业,研究专利制度的经济学意义是非常迫切和必要的。文章在前人的基础上,指出专利制度在微观上是从长、宽、高三个维度对技术创新进行激励的。 The developed countries in the West have studied the economics of the patent system quite a bit, while our country is still in its infancy. China has acceded to the WTO and faced with an increasingly fierce and cruel international market. Trade barriers will soon be shifted from administrative barriers and tariff barriers to non-tariff barriers with technological barriers as the center. For the international market, competition is in a weak position Of the Chinese enterprises, the economic significance of studying the patent system is very urgent and necessary. On the basis of the predecessors, the article points out that the patent system at the microscopic level stimulates technological innovation from three dimensions: length, width and height.
