Abstract ：
The high-quality economic growth of tourism is intimately related to a city's overall strength, and urban resilience is an important index to measure the comprehensive strength of a city. Therefore, determining how to enhance the construction of urban resilience, improve the quality of tourism development, and promote the coupling coordination of these two systems has attracted academic attention in recent years. Based on the panel data of 13 cities in the Beijing-Tianjin-Hebei region from 2010 to 2021, an entropy weight method, coupling coordination model, and obstacle degree model were used to analyze the coupling coordination degree, spatiotemporal evolution characteristics, and obstacle factors between urban resilience and the tourism economy. The results show the following: (1) Urban resilience and tourist economic development levels in the Beijing-Tianjin-Hebei region show an overall upward trend, and both of them show obvious spatial differences. (2) The coupling coordination degree of urban resilience and the tourism economy shows a trend of first rising and then declining in the temporal dimension, while it shows a spatial differentiation pattern of "high in the middle and low in the surrounding area" in the spatial dimension. (3) The obstacle degree structure of the coupling coordination of urban resilience and the tourism economy in the Beijing-Tianjin-Hebei region is relatively stable, with economic resilience as the leading obstacle in the urban resilience system and tourist economic development benefits as the leading obstacle in the tourism economy system. In the future, the Beijing-Tianjin-Hebei region needs to strengthen regional cooperation, enhance the driving role of central cities, continuously improve urban resilience, and promote the high-quality development of the tourism economy.

Abstract ：
In order to balance the economic development and ecological impact of tourism, it is essential to study tourism eco-efficiency in the context of sustainable development. This study analyzed regional tourism eco-efficiency based on the panel data of the 13 cities of the Beijing-Tianjin-Hebei region using the super-SBM DEA model. Then, we analyzed the driving factors, compared regional differences, and investigated influencing factors of tourism eco-efficiency by applying the global Malmquist-Luenberger (GML) index, Theil index, and geographically and temporally weighted regression (GTWR) models. The results demonstrate the following: (1) The overall tourism eco-efficiency in the Beijing-Tianjin-Hebei region between 2010 and 2019 was low, but it had an increasing trend. (2) The advancement of technological progress factors was mostly responsible for the increase in tourist eco-efficiency. (3) The results for tourism eco-efficiency were significantly polarizing, but the gap among the 13 cities is gradually narrowing. Regional differences are the main contributors to differences in tourism eco-efficiency. (4) Per capita GDP, the proportion of tertiary industry in GDP, the number of patents granted, and the proportion of urban population in the total population were the main factors affecting tourism eco-efficiency. This study could serve as a model for similar countries and regions seeking to enhance tourism eco-efficiency and achieve the Sustainable Development Goals.

Abstract ：
In recent years, Beijing has been more often confronted with serious haze pollution, especially in autumn and winter. The People's Government of Beijing Municipality has adopted a package of measures to control the haze pollution with its best efforts. To objectively evaluate how effective these haze pollution control measures are from different perspectives and in an all-round way, it is necessary to adopt a scientific and reasonable approach. Based on the Balanced Scorecard (BSC) idea, we establish a system of indexes to evaluate the government performance of Beijing in haze pollution control from the four perspectives of development quality, public services, government management and development potential, and use a combination of analytic hierarchy process (AHP) and entropy weight method (EWM) to determine the index weights, and objectively evaluate Beijing's performance in haze pollution control from 2010 to 2016. The results show that the scores for the four perspectives are all on the rise, and since the implementation of the Air Pollution Prevention and Control Action Plan in 2013, the government's haze pollution control measures have achieved significant results, and made a much higher overall score. On that basis, we propose the optimized path for Beijing's haze pollution control, namely, accelerating the upgrading of development quality, improving the public services level, strengthening the government management, tapping the development potential of haze pollution control and increasing the linkage and cooperation between the governments of Beijing, Tianjin and Hebei.

Abstract ：
机器学习模型拟合效率高,能够克服多维度和高度非线性等问题,在大气污染物浓度预测中的应用非常广泛。为更好的反映北京市雾霾天气状况,本文采用高精度拟合的BP网络预测模型,建立了基于BP神经网络的雾霾预测模型。首先,建立影响雾霾因素之间的指标体系。其次,采用2018年11月全月天数的大气污染物数据作为训练样本,建立神经网络雾霾预测模型。最后,基于BP神经网络对12月全月天数的PM_(2.5)浓度进行预测。结果表明,在小样本数据下,该模型可以较准确的预测PM_(2.5)的浓度变化趋势,为有关部门对空气质量进行监测和预报提供参考。

使用PCA算法与MLR模型实证分解2002—2016年重载货车污染对北京市严重空气污染天气形成的作用路径与贡献度。由方差分析结果,DHDT、DPM、DNO、DGTKM的方差贡献度均在50%以上,暗示省际公路货物周转需求是引起重载货车数量与行驶里程增加的关键因素,由此引起大量柴油消耗并显著提高北京市NO_2与PM_(10)、PM_(2.5)浓度。系数估计结果显示,重载货车数量、省际货物周转量、NO_2浓度与PM_(10)、PM_(2.5)浓度显著相关,重载货车污染综合变量与CO浓度、柴油消耗量每提高1个标准单位会使北京市重空气污染天数增加1.489个标准单位。因此,在重载货车污染因素中,重载货车...
