Abstract

As an important coastal port city in China, Lianyungang is typical and exemplary in promoting the collaborative process of ecological environment governance and high-quality economic development. Based on the time series data of Lianyungang from 2016 to 2024, this paper constructs the ecological environment index and the high-quality economic development index, and systematically reveals the dynamic interaction mechanism of the two through VAR model, Granger causality test and impulse response analysis. The study found that the impact of high-quality economic development on the ecological environment showed the characteristics of "short-term negative and long-term positive". At the initial stage, the adjustment of industrial structure may aggravate the environmental pressure, but with the application of green technology and industrial upgrading, its positive effect gradually strengthened, and finally formed a continuous promoting effect. The impact of ecological environment on economic development shows the "alternating fluctuation" effect. In the short term, ecological governance promotes economic quality and efficiency by forcing industrial transformation. In the medium term, the withdrawal of traditional production capacity may inhibit economic vitality. In the long term, sustainable economic growth is achieved by relying on the value transformation of ecological resources and the rise of green industries. The interaction between the two has significant time lag and nonlinear characteristics, indicating that policy intervention needs to take into account dynamic balance.
