产业转移是发达地区寻找新的产业发展空间,欠发达地区加速经济、技术追赶,实现区域一体化发展的重要途径。伴随着产业转移的既有人才、技术溢出的正效应,也有环境、污染溢出的负效应。文章以中部六省为研究样本,以全要素生产率指数和污染减排指数为核心变量,通过建立空间技术溢出效应模型和空间环境溢出效应模型,来研究区际产业转移中的技术和环境双溢出效应。研究结果表明:近年来,中部各地区的技术进步主要由区域内的R&D投入决定,由国内和国外产业转移带来的技术溢出效应不明显,但是在产业转移过程中,由国内区际产业转移带来的污染溢出却是比较显著的。这说明近几年,中部地区产业转移的质量不高,从沿海发达地区转移过来的主要是劳动密集型产业而不是技术密集性产业,是属于产业链的低端产业而不是高端产业,造成对环境的压力增大。中部六省在加快提升自身承接产业转移能力的同时,应合理改善招商引资结构,审慎对待境内外投资。
Industrial transfer is an important way to find new industry development space for developed areas, accelerate economic and technological catch-up and realize regional integration development for underdeveloped areas. With the industrial transfer process, not only have the positive effects of human capital and technology spillover, but also have the negative effects of environment and pollution overflow. This paper takes the six provinces in Central China as the research samples, uses total factor productivity index and pollution reduction index as the core variables, through the establishment of space technology spillover effects model and space environment spillover effects model to research the spillover effects of technology and environment in regional industrial transfer. The results show that the technical progress in the six provinces in Central China is mainly decided by the regional RD investment in recent years, the technology spillover effects brought by the domestic and foreign industry transfer are not obvious, but in the process of industrial transfer, the pollution spillover from domestic industry transfer is significant. It shows that in recent years, the industrial transfer quality of the central regions is not high, industrial transfer from the coastal developed areas is mainly labor-intensive industries instead of technology-intensive industries, mainly the low-end industries instead of the high-end industries in the industrial chain, which increases the pressure on the environment. The six provinces in Central China should be reasonable to improve the structure of attracting foreign businesses and investment,have a prudent treatment in domestic and foreign investment when accelerating their ability to undertake industrial transfer.
