Environmental awareness and household energy saving of Chinese residents: Unity of knowing and doing or easier said than done?

Household energy saving is important for the realization of emission peak, carbon neutrality, and energy security goals in China. However, no conclusion has been reached on whether public environmental awareness can promote household energy saving. There are two major defects in previous studies. One is that they focus on the public intention to save energy rather than the real behavior; the other is that the endogenous problem caused by the measurement bias of environmental awareness is ignored. Based on China Family Panel Studies (CFPS) database, this study selects the change in average monthly household electricity charge and electricity consumption as the proxy variables of energy saving, and introduces the public perception level of social security and government corruption as the instrumental variable of environmental awareness. It is found that improvement of environmental awareness has statistical significance for household energy saving and there is still a lot of room for improvement. This conclusion keeps valid in several robustness tests. Further analysis shows that improvement of environmental awareness is more likely to promote energy saving in rural households, male household heads, and young people; and that education and income have a joint moderating effect on the energy saving effect of environmental awareness.     

低轨时差频差系统对运动目标的定位能力

战场高速运动目标往往具有高威胁性，现有天基电子侦察手段对此类目标的定位跟踪能力已经难以适应现代战场感知需要。通过研究时差频差定位原理，在现有双星体制基础上构建了三星时差频差定位体制；同时结合卡尔曼滤波算法，实现了对空中高速运动目标的定位和速度估计。经计算仿真，系统对空中高速运动目标的定位精度达到了几公里量级，速度估计误差达到了10 m/s量级，充分验证了方法的工程可行性。通过上述改进，大幅扩展了天基时差频差系统的应用范围，将有力提升天基系统的战场感知能力。     

The impact of regional ICT development on job quality of the employee in China

The paper matches the province-level ICT development with the micro-level data of the China Family Panel Studies (CFPS), uses multiple indicators to measure ICT development and job quality, and investigates the impact of regional ICT development on job quality of the employee. The research conclusions are as follows: First of all, ICT development has a significant positive impact on job quality of the employee. After a series of robustness tests and dealing with endogeneity issues, the research conclusion continues to be valid. Second, when the job quality of the employee is poor, the promotion of ICT development is relatively strong. Third, ICT development has an indirect impact on job quality through the Internet awareness. Finally, ICT development has a relatively strong role in promoting job quality of women, older, non-agricultural, and medium-skill employees. From the policy perspective, in order to improve the job quality of the employee, we suggest promoting ICT development, narrowing the digital gap, increasing investment in education, and taking into account the different characteristics of employees.     

气候变化信息来源对农户适应性耕作行为决策的影响——来自湖北省水稻主产区的经验证据

目的 适应性耕作行为是农户应对气候变化的关键策略。文章旨在探究气候变化信息因素和信息来源对农户适应性耕作行为存在的潜在影响。方法 通过构建“气候刺激—信息干预—适应行为”理论分析框架，阐明了政府部门、科研机构和邻里交流3类典型信息来源影响农户适应性耕作行为的内在机理。在此基础上，基于湖北省水稻主产区920户稻农的样本数据对理论猜想展开实证检验。结果 （1）来源于政府部门和科研机构的气候变化信息对农户适应性耕作行为有显著的正向影响，但在同时考虑3种信息来源的情景下，科研机构信息来源对农户的适应性耕作行为的正向影响最为强烈。（2）农户在获得政府部门、科研机构和邻里交流的气候变化信息后，他们在气候变化适应性耕作行为方面差异主要取决于其气候变化认知而非主体信任因素。结论 政府部门和科研机构等为代表的正式组织的气候变化信息对农户适应性耕作行为的积极影响更为显著，但这种影响很大程度上取决于农户所获得的信息能否提高其气候变化认知。     

A social media analysis of travel preferences and attitudes,before and during Covid-19

Covid-19 created tremendous uncertainty in the tourism industry; in this study, we use social media data to explore differences in the preferences and attitudes of tourism consumers, both before and during the pandemic. We use natural language processing (NLP) techniques to analyze over one million Reddit posts on travel-related subreddits. We investigate the preference for city and nature-oriented tourism in selected destinations; the analysis demonstrates that nature tourism gained interest during Covid-19 in destinations with rich nature resources, whereas city tourism lost interest in destinations known for city tourism. We also classify Reddit authors into two categories: conservation and openness, according to a psychological theory of personal values, and show that this is predictive, with openness associated with positive travel sentiment and low risk awareness. This points to the potential for value-based segmentation of travel consumers based on theoretically-grounded NLP analysis of social media data.     

Corporate social responsibility and corporate tax avoidance: The channel effect of consumer awareness

This paper investigates the relationship between corporate social responsibility (CSR) and corporate tax avoidance and the impact of consumer awareness on the constructs. We show that consumer awareness has the effect of decreasing the positive relation between CSR ratings and tax avoidance levels. Our findings are robust to various measures of our constructs. Collectively, the findings of this study lend credence to the risk-management view of CSR and demonstrate that consumer awareness acts as a behavioral intervention and governance mechanism to help mitigate corporate hypocrisy.
