技术进步区分为三种类型:引进生产型、引进技术型和自主创新型。在长三角地区,引进生产型(外商直接投资)技术进步和自主创新型(购买国产投资品)技术进步的贡献率均有下降的趋势,而引进技术型(购买进口投资品)技术进步的贡献率则有提高的趋势。用城镇居民人均可支配收入和平均工资分别占人均产值的比重衡量技术进步的福利水平,浙江的福利最高,江苏次之,上海最低。长三角地区江、浙、沪三地技术进步贡献率的差别,是各地域根据比较优势的原则组织生产在竞争中自然形成的结果。鼓励技术进步的政策要全面考虑技术进步的各种类型。
Technological progress is divided into three types: the introduction of production, the introduction of technical and independent innovation. In the Yangtze River Delta region, the contribution rate of technological progress in introducing production-oriented (FDI) technology and independent innovation (purchase of domestically produced investment products) all showed a downward trend, while the contribution of technological advances in the import of technology-based (purchase of imported investment products) Rate is to increase the trend. The per capita disposable income and average wage of urban residents, respectively, as the proportion of per capita output value of technological progress to measure the level of welfare, the highest welfare in Zhejiang, Jiangsu, followed by Shanghai, the lowest. The differences in the contribution rate of technological progress in Jiangsu, Zhejiang and Shanghai in the Yangtze River Delta are the natural results of the formation of competition by the various regions according to the principle of comparative advantage. Policies that encourage technological progress must take full account of the various types of technological progress.
