摘要: 在系统分析农产品加工业集聚对环境污染的非线性影响及数字经济在其中起到的调节机制基础上,利用2010~2020年长江经济带11个省市的面板数据,运用熵值法和区位熵指数测度了农产品加工业集聚水平、环境污染指数,采用面板固定效应模型实证检验了农产品加工业集聚对环境污染的影响机制,并进一步检验了数字经济在该影响过程中的调节效应。研究结果表明:农产品加工业集聚与环境污染之间存在显著“倒U型”曲线关系,数字经济在农产品加工业集聚影响环境污染的过程中存在明显的抑制调节作用。区域异质性检验表明,长江中游地区农产品加工业集聚对环境污染的作用处于“倒U型”曲线左侧,即农产品加工业集聚水平的提升正在加剧环境污染,下游地区农产品加工业集聚对环境污染的作用已转移到“倒U型”曲线右侧,即对环境污染产生抑制作用,而上游地区农产品加工业发展仍较薄弱,对环境污染的促增作用尚未显现;长江上游地区数字经济在农产品加工业集聚影响环境污染的过程中发挥着显著的抑制作用,调节效应显著,中下游地区调节效应不显著。鉴于此,应大力发展农产品初、精深加工,加速推进农产品加工业生态化、集约化发展,通过数字化升级推动实现流域生态文明。

Abstract: On the basis of systematic analysis of the non-linear impact of agglomeration of agricultural product processing industry on environmental pollution and the regulatory mechanism of digital economy, this paper used the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2010 to 2020 to measure the level of agglomeration of agricultural industry and environmental pollution index, by the entropy method and location entropy index. The panel fixed effect model was used to empirically test the impact mechanism of agglomeration of agricultural industry and the moderating effect of the digital economy. The research results indicated that there was a significant "inverted U-shaped" curve relationship between agglomeration of agricultural industry and environmental pollution. The digital economy had a significant inhibitory and regulatory effect on the process of agglomeration of agricultural industry. The regional heterogeneity test showed that the role of agglomeration in environmental pollution in the middle reaches of the Yangtze River was on the left side of the "inverted U-shaped" curve, indicating that the improvement of agglomeration was exacerbating environmental pollution. The role of agglomeration in downstream areas shifted to the right side of the "inverted U-shaped" curve, indicating an inhibitory effect on environmental pollution. However, the development of agricultural industry in upstream areas was still relatively weak, The promoting effect on environmental pollution had not yet emerged; The digital economy in the upper reaches of the Yangtze River played a significant inhibitory role in the process of agglomeration of agricultural industry, with a significant regulatory effect, while the regulatory effect in the middle and lower reaches was not significant.In view of this, we should vigorously develop the primary and intensive processing of agricultural products, accelerate the ecological and intensive development of agricultural products processing industry, and promote the ecological civilization through digital upgrading.
