Evaluation and drive mechanism of tourism ecological security based on the DPSIR-DEA model

Tourism ecological security evaluation is a critical way of measuring the sustainable development of tourism destinations. Based on ecological system theory, this study creates a new comprehensive evaluation model, Driver-Pressure-State- Impact-Response-Data Envelopment Analysis (DPSIR-DEA), to measure tourism ecological security, which is an evaluation of Quality from the perspective of Efficiency. The Yangtze River Delta (YRD) is chosen as the study site, and methods including Geo-Detector and spatial autocorrelation are used to analyze space-time law and influence factors. Results indicate that the spatial differentiation pattern of southeast-northwest is gradually presented from hot-spot to cold-spot. Moreover, some critical impact factors affecting tourism ecological security are identified, including third-industry growth rate, tourist density, etc, and the driving mechanism is constructed. We not only introduces a new evaluation of tourism ecological security but also explores the crucial impact indexed and the driving mechanism.
