Taking the companies listed on the Shenzhen Stock Exchange from 2018 to 2022 as research objects, a two-way fixed-effects model was constructed to explore the relationship between IBF, quality of information disclosure and enterprise innovation efficiency through empirical analysis, and the main research hypotheses were tested for robustness. It is found that the implementation of IBF can significantly enhance the innovation efficiency of enterprises, and the quality of information disclosure plays a partial mediating role between IBF and enterprise innovation efficiency. The study provides a new perspective for understanding the association mechanism between IBF and enterprise innovation efficiency, which is of theoretical and practical significance for promoting enterprise innovation development.

From the perspective of ESG(environmental, social, and governance), enterprise value creation integrates economic, social, and environmental values. Corporate value creation was measured from three aspects of economic, social, and environmental. There is a positive correlation between ESG performance and corporate value creation. Corporate reputation plays an intermediary role.The quality of internal control has a positive moderating effect on the relationship between ESG performance and corporate value creation. The positive relationship between ESG performance and corporate value creation is more significant in samples of non-state-owned enterprises, enterprises with strong innovation capabilities, high media attention, and high industry competition.

Low-carbon evaluation is a process of comprehensively assessing the environmental behavior and performance of enterprises, which helps to shape their positive environmental image and enhance their sense of social responsibility. In the context of low carbon economy, enterprise performance assessment involves not only quantitative indicators but also qualitative indicators. By constructing a hybrid multi-attribute performance evaluation index system, the uncertainty data of non-quantitative indicators of low-carbon enterprises were evaluated by trapezoidal fuzzy numbers, and the fuzzy entropy weighting method was used to determine the weights of the indicators, and then the multi-criteria weighted aggregation method was used to calculate the comprehensive performance evaluation value of the enterprise. Finally, the enterprise’s low-carbon development level can be ranked according to the fuzzy credibilistic mean and variance of performance.

Most of the conventional topographic map drawing methods adopt the principle of tilt photography real scene 3D model, which is more suitable for land area survey and drawing. The application effect in the water area topographic map drawing is poor, the plane error of the topographic map is large, and the drawing accuracy is low. Based on this, a new rendering method was proposed by introducing the principle of digital aerial photogrammetry. Firstly, digital aerial photography parameters was designed, including ground sampling distance(GSD), altitude, and image overlap. Then, image control points was set up and global navigation satellite system real time kinematic(GNSS-RTK) technology was used to measure the coordinates of the image control points. On this basis, the digital aerial photogrammetry technology was used to obtain the plane and elevation elements of the topographic map respectively, and then the topographic map was drawn. The experimental results show that the new method is highly feasible, its plane mean square error is small, the maximum is not more than 0.091 m, and the accuracy of topographic map drawing is high.

In order to accurately evaluate the operation safety level of civil aviation transportation airport apron, the evaluation index system was established based on “man-machine-environment-management”, the evaluation index system was verified by using the structural equation model, and the entropy weight method was used to carry out subject-objective assignment. The combination of assignment was conducted based on the game theory, so as to put forward the transportation airport apron safety evaluation model based on the SEM(structural equation model)-entropy weight method and the extension cloud model. Chengdu Shuangliu Airport was used as an example for verification, and the results show that the apron operation safety level of this transportation airport is good, which is in line with the actual operation situation, and the evaluation model can provide a scientific and feasible reference method for the evaluation of the apron operation safety of civil aviation transportation airports.

The finite-element model was used to simulate the double I-steel and concrete composite beam bridge with a span of 4×35 meters in the approach bridge outside the dike of Shouchun Huaihe River Bridge.The results indicate that the impact factor of the steel beam increases with speed and then decreases, reaching a maximum at 60 km/h. In contrast, the impact factor of the bridge deck continues to rise with speed, exceeding the design value of the standard local impact factor by 91.67% at 120 km/h. Both the steel main beam and the bridge deck’s impact factors decrease with the increase in vehicle weight. Specific trends in the variation of impact coefficients with vehicle speed and weight are identified, the limitations of existing bridge design codes in accurately describing the actual dynamic response to vehicle loading is revealed, the importance of considering local dynamic effects in bridge design and evaluation is emphasized.

In order to ensure the efficient development and safe operation of deep water gas field and fully release the production capacity of each well area, the integrated steady-state model of “wellbore-wellhead-manifold-platform” was established. Based on the production plan, the research was carried out from the aspects of production verification, hydrate prevention and control, slug analysis and liquid carrying analysis. The results show that there are hydrate production risks in the whole life cycle in the east and west production routes. The maximum hydrate sub-cooling degree in the production route is less than -5 ℃ by optimizing the MEG injection amount in each well. The platform temperature of eastern and western logistics is -2.4~9 ℃, and the platform pressure is 1.3~11 MPa.The research results can provide technical guidance for the effective development of similar deep water gas fields in the future.

Engineering projects are the core body of cooperation among countries along the “Belt and Road”. Mainly considering the environmental factor index, a national project construction cooperation factor evaluation system constructed, including 5 first-level indexes, 10 second-level indexes and 27 specific indexes.
