产业一体化的绿色发展效应——以长江中游城市群为例

The Green Development Effect of Industrial Integration: A Case Study of the City Group in the Middle Reaches of the Yangtze River

摘要:

架构产业一体化影响城市绿色全要素生产率(GTFP)逻辑框架的基础上,运用SVR算法、SBM-DEA模型、耦合协调度模型和PVAR模型研究了长江中游城市群产业一体化对GTFP的影响效应。结果显示：2004—2017年,产业一体化与GTFP均表现波动上升趋势且呈中度协调状态,但产业一体化整体滞后于绿色经济发展；长期来看,产业一体化对GTFP具有显著的正向影响,但其逆向过程并不明显；短期来看,产业一体化对GTFP的驱动作用由强转弱,GTFP对产业一体化的冲击效应却始终微弱,说明产业一体化是GTFP的直接驱动变量,相反则不成立。

Abstract:

Based on the logical framework of industrial integration affecting urban green total factor productivity (GTFP), the SVR algorithm, SBM-DEA model, coupling coordination degree model and PVAR model are used to study the impact of industrial integration on GTFP in the middle reaches of the Yangtze River. The results show that from 2004 to 2017, industrial integration and GTFP both showed a fluctuating upward trend and were in a moderately coordinated state, but the overall industrial integration lags behind the development of green economy; in the long run, industrial integration has a significant positive effect on GTFP However, the reverse process is not obvious; in the short term, the driving effect of industrial integration on GTFP turns from strong to weak, but the impact of GTFP on industrial integration is always weak, indicating that industrial integration is a direct driving variable of GTFP. The opposite is not true.
