Due to the continuous deepening impact of the COVID-19 pandemic on the global economy and the exacerbation of the "triple overlapping" situation in China, there has been a significant increase in employment pressure and dynamic changes in a considerable number of migrant workers. This has brought about new situations and problems for the economic and social development of urban and rural areas. The urbanization of rural migrant workers is a systematic project involving multiple sectors and departments such as development and reform, finance, education, housing, human resources, and culture. It requires systematic research and coordinated promotion.This study provides a basic overview of the employment policies for the new generation of migrant workers in China in "three stages" and analyzes the main challenges and reasons faced by these workers in terms of employment policies. By summarizing and organizing the employment policies released at the national level in China since 2008, using the grounded theory and data envelopment analysis model, input and output indicators for employment policies and the urbanization of the new generation of migrant workers are deduced and summarized. The data envelopment analysis model is used as an evaluation tool for the efficiency of employment policies in promoting the urbanization of migrant workers. The results show that the employment policies currently implemented in China have played an important role in improving the urbanization of migrant workers, and the degree of urbanization is increasing year by year. The direction of policy formulation and implementation is completely correct, so policy investment should be further increased along the current direction, and policy items should be refined and enriched to further promote the speed and quality of the urbanization of migrant workers.Specifically, the years 2009, 2010, and 2011 were the main periods of analysis. Considering the historical background and employment policies at that time, the economic growth was slow during the post-financial crisis era, and the overall economic environment was depressed. Although the government proposed proactive employment policies in 2008, the actual implementation of these policies lacked clear instructions on how to guarantee the welfare, safety, and other protections for migrant workers in non-standard employment regulated by the market. Therefore, the employment policies in this stage were still in the exploration phase. The overall efficiency showed improvement in 2010 and 2011, mainly driven by market conditions, but the interaction between policy resource input and market factors was relatively weak. Analyzing the efficiency input and output adjustments of employment policies in years where data envelopment analysis was ineffective, it was found that the number of employed and income levels of the new generation of migrant workers reached an optimal state in 2011, aligning with the level of socio-economic develo

With the method of big data mining, this research makes a comparative analysis on the operation capability of tourism listed companies, and analyzes the impact of Covid-19 on the operation ability of tourism listed companies. The conclusion of the analysis shows that Covid-19 had some negative impacts on the business performance of tourism companies, which caused declines and decreasing trends. But the companies which can focus on main businesses, expand to new areas, enhance the process of product information construction, and promote the cooperation between finance and the government, will get better business performance.

The online learning information ecosystem gives full play to the advantages of electronic education, makes full use of educational resources, and maximizes the value of educational resources. In this paper, from the four dimensions of educators, educators, online teaching content and online teaching environment, this paper establishes 20 influencing factors for the stable operation of university network education information ecosystem. And by using the interpretive structural model method, the relationship between any two influencing factors is determined, the adjacency matrix is constructed, the reachability matrix is calculated by Python software, and then the reachability matrix is decomposed to form the interpretive structural model framework of influencing factors for the stable operation of university network education information ecosystem. On this basis, the influencing factors are defined as three levels. They are surface layer, middle layer and deep layer, and the interpretive structural model level is analyzed in turn. Finally, it puts forward countermeasures and suggestions to promote the stable operation of university network education information ecosystem, and provides guidance for the sustainable and stable development of university network education information ecosystem.

Abstract: Because of the poor effect of traditional small target detection, by analyzing the characteristics of small targets, taking RESNET of deep separable convolution as the feature extraction network, a small target detection algorithm based on RESNET of deep separable convolution is proposed. In order to ensure that the network has good adaptability and strong small target feature extraction ability, the algorithm adopts the topology of the multi convolution kernel. The convolution form of the network is improved by packet convolution to reduce the number of network parameters and computation, and the improved channel shuffling is used to enhance the exchange of feature information between different packets and splice the output features. Finally, combined with the residual connection form, a deep separable packet convolution RESNET network (mower) with multiple convolution cores is formed. The experimental results of the DOTA data set show that the Top1 error rate and top5 error rate of the RESNET network based on deep separable convolution are 30.68% and 8.75%, respectively, which is 3.34% and 1.56% lower than that of traditional RESNET network. The complexity of the model is also reduced, which has obvious advantages over other network models.
