This study conducts a comprehensive comparative analysis of machine learning models for customer churn prediction, focusing on the U.S. context. The research evaluates the performance of logistic regression, random forest, and neural networks using industry-specific datasets, considering the economic impact and practical implications of the findings. The exploratory data analysis reveals unique patterns and trends in the U.S. banking and finance industry, such as the age distribution of customers and the prevalence of dormant accounts. The study incorporates macroeconomic factors to capture the potential influence of external conditions on customer churn behavior. The findings highlight the importance of leveraging advanced machine learning techniques and comprehensive customer data to develop effective churn prevention strategies in the U.S. context. By accurately predicting customer churn, financial institutions can proactively identify at-risk customers, implement targeted retention strategies, and optimize resource allocation. The study discusses the limitations and potential future improvements, serving as a roadmap for researchers and practitioners to further advance the field of customer churn prediction in the evolving landscape of the U.S. banking and finance industry.展开更多

It brings about much damaged land and bare slope. It is necessary to restore vegetation and rebuild landscape. In the design of target plant community and configuration plants,it is required to select as far as possible plants that can blossom and bear fruit or pods. Then seeds of these plants can be harvested,processed and sold,and applied for other projects,so as to develop into a complete forest and grass seed industry chain. This not only reasonably utilizes land resources,but also provides a new approach to the problem of insufficient fine forest seed sources in China. This paper discussed the use of land resources in road side slope and forest and grass seed selection and breeding technology,and elaborated the industrialized development paths for forest and grass seed industries in road side slope. Finally,it arrived at following recommendations.( i) The construction of forest and grass industry economic belt using land resources in road side slope can realize maximum land value. Building a road can help people there get rich,and the type of land and water cultivates its type of forest and grass.( ii) It can make up for the losses incurred from construction of expressway and high-speed rail or destroying forest land,and it can increase farmers' income.( iii) It can increase the supply of domestic seeds,reduce seed import,save foreign exchange,and partly solve the problem of insufficient supply of forest and grass seeds.( iv) It is able to form a complete forest and grass seed industry economic cycle chain,increase employment,and provide new approaches for enriching and benefiting farmers.展开更多

The responsibility of an economist is not to object to any kind of industrial policy for fear of failure, nor unconditionally support all kinds of industrial policies because industrial policy is a necessary condition for the success of economic development. An economist should explore the causes behind the success or failure of industrial policies so as to help government reduce the chance of failure and improve the probabilities of success in applying industrial policies. This paper analyzes why industrial policy is necessary for successful economic development. This paper notes that synergy of ＂efficient market＂ and ＂facilitating state＂ is indispensable for economic development, and also analyzes why developed and developing countries failed in applying industrial policies. From the perspective of New Structural Economics, in this paper industries in China are divided into five types： catching-up industries, leading-edge industries, comparative advantage-losing industries, short innovation cycle industries and comparative advantage-defying strategic industries. The paper also analyzes how to formulate effective industrial policy in China. It is noted that, based on the characteristics of each industry, ＂efficient market＂ and ＂facilitating state＂ should both play their respective roles in promoting China＇s industrial transformation and upgrading.展开更多
