數字經濟對可持續發展的影響及其耦合關系

[摘 要：推進數字經濟與可持續協同發展是實現區域經濟高質量發展的客觀要求。文章結合2011—2019年長江中游城市群28個地級市數據，運用PLS模型和耦合協調度模型探討數字經濟對可持續發展的作用機制及耦合關系。結果表明：長江中游城市群數字經濟水平逐年增高，數字經濟主導維度以“電信費用→軟件從業人數→移動電話用戶→互聯網用戶→數字普惠金融”的發展順序轉變；長江中游城市群可持續發展呈逐年上升態勢，且變異系數逐年遞減，總體呈現東高西低的空間格局；移動電話用戶、互聯網用戶、數字普惠金融是驅動長江中游城市群可持續發展的極重要因素；長江中游城市群數字經濟與可持續發展的耦合度、耦合協調度呈上升態勢，兩者具有較好的耦合性，且趨于良好協調性。

關鍵詞：數字經濟；可持續發展；耦合協調度模型；長江中游城市群

Abstract：Promoting the digital economy and sustainable synergistic development is an objective requirement for achieving high-quality regional economic development. Combining the data of 28 prefecture-level cities in the urban agglomeration in the middle reaches of the Yangtze River from 2011—2019，the PLS model and coupling coordination degree model are used to explore the mechanism and coupling relationship of digital economy on sustainable development. The results show that the level of digital economy in the urban agglomeration in the middle reaches of the Yangtze River is increasing year by year. The dominant dimension of digital economy changes in the order of \"telecom expenses→ number of software practitioners→mobile phone users→internet users→digital inclusive finance\"；the sustainable development of the urban agglomeration in the middle reaches of the Yangtze River is rising year by year，and the coefficient of variation is decreasing year by year，showing a spatial pattern of high in the east and low in the west in general；mobile phone users，Internet users，and digital inclusive finance are extremely important factors driving the sustainable development of the urban agglomeration in the middle reaches of the Yangtze River；the coupling degree and coupling coordination degree of digital economy and sustainable development in the urban agglomeration in the middle reaches of the Yangtze River are on the rise，and the two have good coupling and tend to be well coordinated.

Key words：digital economy；sustainable development；coupling coordination model；the urban agglomeration in the middle reaches of the Yangtze River

一、引 言

工業革命4.0將世界經濟重塑為數字經濟［1］。作為繼工業經濟以后的主要經濟形態，數字經濟的廣泛運用促進了經濟可持續發展［2］。近年來，我國數字經濟快速發展，規模從2016年的22.6萬億元上升至2021年的45.5萬億元［3］，在這個過程中，傳統產業的數字化和信息數字的產業化對區域生態環境的可持續發展產生了深刻影響。Yang等［4］研究表明，中國數字經濟每增加1%，綠色發展水平增加0.496%；Hosan等［5］研究發現，數字經濟對中國等新興經濟體的可持續發展具有重要意義。目前，數字經濟在全球47個主要國家創造了近1/2的GDP貢獻，數字技術創新是全球綠色發展的戰略重點［6］。……
