The impact of producer services agglomeration on the development of green economy:based on the urban data of Huaihe ecological economic belt

Based on the panel data of 26 prefecture-level cities in Huaihe ecological economic belt from 2011 to 2019, this paper discusses the impact of producer services agglomeration on the development of regional green economy by use of spatial econometric model from the two dimensions of professional agglomeration and diversified agglomeration. It is found that the diversified agglomeration of producer services can significantly promote the development of regional green economy, while the professional agglomeration of producer services exerts no significant impact; Both are conducive to heighten the quality of the ecological environment in the region, yet the promotion effect of specialized agglomeration is significantly greater than that of the diversified agglomeration. From the different industrial levels, the diversified agglomeration of high-end and low-and-mid-end producer services is conducive to the development of regional green economy, however, the promotion effect of high-end producer services is strikingly more obvious.
