This paper evaluates of the overall situation of China’s energy security. Firstly, analyzes the current situation of China’s energy security. Secondly, according to the Chinese Energy Statistical Yearbook and BP Energy Statistical Yearbook, induces 10 measures. Thirdly, defines the similar weight by similar figures and scores the 10 measures. Finally, the research shows the 10 measures’ security situation, at the same times gives some advices according to the result.

From the perspective of input and output, this paper constructs an evaluation index system for the status quo of technology innovation resource allocation in China’s aerospace industry. Taking the industrial panel data of 20 provincial regions from 2007 to 2016 in China as samples, this paper uses the stochastic frontier method, which is improved by the projection pursuit model based on accelerated genetic algorithm, to analyze the factors influencing the allocation efficiency of technology innovation resource in the aerospace industry and then make a static evaluation for the current situation. In addition, based on the perspective of velocity characteristics, this study uses the dynamic comprehensive evaluation model to evaluate the resource allocation of technology innovation in the aerospace industry. The empirical research shows that the resource allocation efficiency of technology innovation in the aerospace industry is generally at the lower middle level, indicating an unbalanced trend of “reverse” allocation with the level of regional economic development. It is also found that the efficiency improvement effect in recent years is not obvious. At last, based on the study’s findings, some countermeasures and suggestions are put forward to improve the current situation.

To promote the green taxis in Macau SAR has being attractive because of the increasingly air pollution caused by vehicles’ emission. In order to improve the air quality and living condition in Macau, this paper shows us some environmentally friendly taxis to replace theconventional ones. In this paper, an overall picture of the current situation and tendency of world’s taxies is firstly presented. Secondly, the vehicle emissions of Macau taxi including environmentally friendly ones are detailedly demonstrated and compared. On the basis of feasibility, cost, safety and regulations related to Macau, the existing vehicle models are also comprehensively elaborated and evaluated. At the end of the paper, it will predict possible directions of the development of taxis in the near future of Macau. The analysis and evaluations of vehicle models are all considerate of what really Macau is.
