利用中国工业企业数据库对辽宁省1.5万及全国30万个工业企业R&D投入强度及特征进行分析得到:辽宁省工业企业研发投入总量在全国排名第八位,但全部工业企业的研发投入强度只有0.3%,在全国排25位;辽宁省工业企业的研发投入结构具有明显的重工业、国有经济主导特征,年销售收入大于3亿元、占全部工业企业比重1%的特大型工业企业占全部工业企业研发投入总额的83.51%,但其研发投入强度只有0.51%,低于全国同类企业0.91%的平均水平。辽宁工业企业研发强度过低已成为制约辽宁成为科技产出强省的关键因素。
Using the database of China’s industrial enterprises, the intensity and characteristics of R & D investment of 15,000 industrial enterprises in Liaoning Province and 300,000 industrial enterprises across the country were analyzed. The total R & D investment of industrial enterprises in Liaoning Province ranked the eighth in the country, but the intensity of R & D investment of all industrial enterprises was only 0.3%, ranked 25 in the whole country. The structure of R & D investment in industrial enterprises in Liaoning Province has obvious characteristics of heavy industry and state-owned economy. The annual sales revenue is more than 300 million yuan, accounting for 1% of the total industrial enterprises. The total industrial output R & D investment of 83.51% of the total, but its R & D investment intensity of only 0.51%, lower than the national average of 0.91% of similar enterprises. The underdeveloped R & D intensity of industrial enterprises in Liaoning has become a key factor restricting Liaoning to become a province with strong scientific and technological output.
