Based on the legality theory and impression management theory, this paper uses 112 listed companies in polluting industries as the research sample to empirically test the relationship between environmental performance and environmental information disclosure. The study found that: companies will adjust their environmental information disclosure strategies based on current environmental performance; companies with good performance are more inclined to disclose high-quality information that is true and evidence, and companies with poor performance usually perform impression management on environmental reports based on the form and content of disclosure; compared with companies with good environmental performance, companies with poor environmental performance have lower environmental information disclosure quality.
本文基于合法性理论和印象管理理论,以112家污染行业上市公司为研究样本,实证检验了环境绩效与环境信息披露之间的关系。研究发现:企业会根据当前环境绩效调整环境信息披露策略;业绩较好的公司更倾向于披露真实、有证据的高质量信息,业绩较差的公司通常根据披露的形式和内容对环境报告进行印象管理;与环境绩效较好的公司相比,环境绩效较差的公司环境信息披露质量较低。

With the development of complex products, military enterprises face various paradoxical realities, like chaos, complexity and contraction. these are caused by multi-dimensional effects in space and desynchronization effects in time. The management reform is gradually promoted by engineering practice. The management aims to seek a comprehensive and coordinated solution to the process system and capacity building problems. The management system establishes a value system with no goal, no end, but it only has a doer and a growing team. The process can be divided into three parts, including identification, systematic decomposition and compound combination, to realize process fundamental changes, affecting the future state. The case analysis is conducted for fault investigation and repair of military product development process. The practice shows that the method proposed in this paper improves designers ability, condenses the team combat effectively, accelerates the processing process of fault parts, and successfully completes the model development task.
随着复杂产品的发展,军工企业面临着混沌、复杂、收缩等各种矛盾现实。这是由空间上的多维效应和时间上的非同步性效应造成的。工程实践逐步推动了管理改革。管理的目的是寻求一个全面和协调的解决方案的过程,系统和能力建设问题。管理体系建立了一个没有目标、没有终点的价值体系,只有一个实干家和一个成长中的团队。该过程可分为识别、系统分解和复合组合三个部分,实现工艺根本性变化,影响未来状态。对军用产品开发过程中的故障排查与修复进行了案例分析。实践表明,本文提出的方法提高了设计人员的能力,有效地凝聚了团队作战,加快了故障部件的处理过程,成功地完成了模型开发任务。

Due to the long order lead time of the construction and decoration plate production enterprises, the suppliers often fail to deliver the goods in time, which affects the production of the enterprises. At the same time, the overall inventory of the supply chain occupies a large scale, and the capital turnover pressure of plate enterprises is great. First of all, this paper selects the relevant indicators and makes a quantitative analysis of each index with the help of PCA method, and quantifies the order satisfaction rate, supply variance and supply mean. Then this paper uses the principal component analysis PCA method to determine the weight of the above three indicators, in which the order satisfaction rate accounts for the largest weight. On this basis, the quantitative evaluation index system of supplier guarantee enterprise production is established, and the top 50 most important suppliers are solved. This paper constructs the quantitative index system of supplier guarantee enterprise production and the minimum loss of transporters, gives the solution of the optimal supplier and transporter, and sets up the most economical ordering strategy and transshipment strategy. Then the minimum number of transshipment merchants is solved by 0-1 model, and it is found that at least 17 enterprises can meet the demand of production. We establish the most economical raw material ordering strategy based on multi-objective programming model. For the transshipment strategy, by adding the loss rate index optimized by the normalized transshipment number factor, the transfer scheme with the least loss is established based on the dynamic programming strategy, and the optimal transshipment strategy is obtained.
由于建筑装饰板材生产企业的订单交货期较长,供应商往往不能及时交货,影响了企业的生产。同时,供应链整体库存占据规模较大,板块企业资金周转压力较大。首先选取相关指标,利用主成分分析法对各指标进行定量分析,量化订单满意率、供给方差和供给均值。然后运用主成分分析PCA方法确定上述三个指标的权重,其中订单满意率所占权重最大。在此基础上,建立了供应商保障企业生产的定量评价指标体系,求解出最重要的50家供应商。构建了供应商保证企业生产和运输商损失最小的定量指标体系,给出了最优供应商和最优运输商的解,建立了最经济的订货策略和转运策略。然后用0-1模型求解最小转口商家数量,发现至少有17家企业可以满足生产需求。基于多目标规划模型,建立了最经济的原材料订购策略。对于转运策略,通过加入归一化转运数因子优化后的损失率指标,基于动态规划策略建立损失最小的转运方案,得到最优转运策略。

With the development of artificial intelligence technology, remote sensing target detection has gradually become a hot issue in the field of computer vision, which can be widely used in navigation, exploration, disaster warning, etc., and it has important research significance and application value for remote sensing target detection. However, the scale difference of remote sensing targets makes detection very difficult. Therefore, we propose a feature re-fusion network based on YOLO-FRN-YOLO. Based on the original three detection layers of YOLO, by re-fusing the features of the three output layers of the backbone, each feature layer can be deeply combined with The semantic information before sampling or after sampling, and the depth of the detection layer after feature re-fusion retains the semantic information of targets of different scales, and improves the detection ability of targets of different scales. The results show that on the RSOD datasets, the average precision of our method exceeds YOLOv3, and it is also better than other advanced networks.
随着人工智能技术的发展,遥感目标检测逐渐成为计算机视觉领域的热点问题,可广泛应用于导航、探测、灾害预警等领域,遥感目标检测具有重要的研究意义和应用价值。然而,遥感目标的尺度差异给探测带来了很大的困难。因此,我们提出了一种基于YOLO-FRN-YOLO的特征再融合网络。在YOLO原有的三个检测层的基础上,通过对主干三个输出层的特征进行再融合,每个特征层都可以与采样前或采样后的语义信息进行深度结合,特征再融合后的检测层深度保留了不同尺度目标的语义信息,提高了对不同尺度目标的检测能力。结果表明,在RSOD数据集上,我们的方法的平均精度超过了YOLOv3,也优于其他先进的网络。

Due to the increasingly significant competition inside and outside the aviation industry, airlines choose to conduct personalized sales to passengers for the purpose of increasing economic efficiency. In this paper, we select airlines customer information data during the period from 2012 to 2014, segment the value of air customers based on the LRFMC model and K-means algorithm. Then establish an airline customer churn prediction model, define churn customers, select characteristics, train SVM, Adaboost, RandomForest and Xgboost models, and then identify churn customers. Finally, the four models are compared and the optimal model is obtained. This article aims to classify airline customers so that airlines can adopt different marketing strategies for customers of different values to maximize profits. Improve the problem of customer churn, enable airlines to maintain their own markets, and bring high profits to airlines.

Venture capital network reveals co-investment relationships between investors. The comprehensive analysis of its structure could not only detect the investment preference of each investor, but also uncover some hidden patterns within their cooperation's engagement. In this paper, we construct two networks-one directed and another undirected-with nodes as investors and edges as their collaboration relationships to analyze the investor networks from different perspectives. We first analyze two networks based on conventional techniques from graph theory such as community detection and PageRank centrality and obtain some interesting findings concerning the patterns of decision-making and each investor's prestige. Given such indicative discovery, we also attempt to predict investors' characteristics with Graph Convolutional Network (GCN) and Personalized Propagation of Neural Predictions (PPNP) by encoding each investor's information into a vector embedding. The results once again display the power and advantages of these two emerging neural networks, and it would also facilitate further research and analysis.
风险投资网络揭示了投资者之间的共同投资关系。对其结构进行综合分析,不仅可以发现各投资者的投资偏好,还可以揭示其合作参与中隐藏的一些规律。本文构建了两个有向和无向网络,以节点为投资者,以边缘为其协作关系,从不同角度分析了投资者网络。我们首先分析了基于图论的传统技术(如社区检测和PageRank中心性)的两个网络,并获得了一些关于决策模式和每个投资者声望的有趣发现。鉴于这一指示性发现,我们还尝试通过将每个投资者的信息编码到向量嵌入中,使用图卷积网络(GCN)和个性化神经预测传播(PPNP)来预测投资者的特征。这一结果再次显示了这两种新兴神经网络的强大和优势,也为进一步的研究和分析提供了便利。

An accurate forecast of Neijiang's regional gross domestic product is vital important for the construction of the Chengdu-Chongqing economic circle to some extent. In this work, a new grey model is proposed and applied to the regional gross domestic product of Neijiang city. The Neijiang city is in a superior geographical position in the construction of Chengdu-Chongqing economic circle. In this paper, firstly a discrete grey prediction model with hyperbolic sine driving term is proposed based on the corresponding continuous model. Secondly, the recursive function of the discrete model is deduced through the recursive formula, and then the parameter values of the model are calculated by the least square method. Finally, the trend of the regional gross domestic product of Neijiang city is predicted by the new model along with other forecasting models. By comparing results of these models, it is proved that the grey discrete model with hyperbolic sine driving term has higher accuracy.
准确预测内江区域生产总值对成渝经济圈建设具有重要意义。本文提出了一种新的灰色模型,并将其应用于内江市区域生产总值。内江市在成渝经济圈建设中处于优越的地理位置。本文首先在相应的连续模型的基础上,提出了一种带有双曲正弦驱动项的离散灰色预测模型。其次,通过递推公式推导离散模型的递推函数,然后利用最小二乘法计算模型的参数值;最后,结合其他预测模型对内江市区域生产总值的变化趋势进行了预测。通过比较这些模型的结果,证明了带有双曲正弦驱动项的灰色离散模型具有较高的精度。
