Authors: Ning Wang , Zhao Li
Published: April 2021

Over more than forty years of deepening reform and opening up, China has become the second largest world economy after the United States. As a component of energy system in China, rural energy is becoming more and more important. With the development of rural economy in China, the efforts of energy conservation and emission reduction have been continuously strengthened and expanded in China. Sustained, safe, and green energy supply is the material basis for the sustainable development of rural economy in China, and it is also a prerequisite for improving the quality of life of rural residents in China. Given living habits and income levels, energy consumption in rural areas in China is still dominated by traditional energy sources such as coal and firewood. There is little use and consumption of new energy. Rural energy is gradually declining for the investment in special funds for rural energy projects is not enough. New energy technology research and development are lagging. At the same time, rural areas have low using efficiency but high demand of energy, which leads more contradictions. In order to meet the needs of farmers for energy production and increase their income, it is necessary to study the countermeasures of rural energy development, which becomes an important part of the construction of a new socialist countryside. Based on the analysis of rural energy developing status and rural energy consumption structure in China, this article pointed out the problems including unreasonable energy structure, insufficient supply, the contradiction between supply and demand, and the lagging construction of follow-up service management system, and uncompleted energy support policies and imperfect incentive measures. We also put forward corresponding countermeasures and suggestions.

Hate Crime Analysis based on Artificial Intelligence Methods
Authors: Wang Shaoxuan
Published: April 2021

Hate crimes always take a toll on American citizens, which harms social security. It is essential for researchers to explore the factors, which lead to hate crimes. This research is to find out the relationship between hate crimes and factors including income inequality, median household income, race using Machine Learning methods. Machine Learning, as an important branch in Artificial Intelligence, is a good way for finding relationships between things. The research is based on a dataset of hate crimes rates in the 2016 U.S. presidential election as well as hate crimes rates in every U.S. state from 2010 to 2015. Simply linear regression and multiple linear regression are used to describe the factors that influence the crime rate and their contributions, such as share of white poverty or share of non-white residents, or the median household income. Then, K-means is applied to classify hate crimes into 5 levels according to the crime rate. Furthermore, KNearest Neighbors is used to demonstrate a prediction of hate crime. At last, a histogram is applied to indicate the variance of the hate crimes in different states. From linear regression, four highest correlation coefficients with a hate crime can be found out, which are income inequality, median household income, the share of noncitizen, and race in turn. Income inequality has the highest correlation coefficient with a hate crime. From multiple linear regression, it can be found out that only by implementing income inequality, median household income, and race can we obtain the highest R square values, which are 0.44 for 2010 to 2015 hate crimes and 0.33 for 2016 hate crimes. From the K-Nearest Neighbors method, hate crimes can be predicted with an accuracy of 40% by applying median household income. Adding the race factor, accuracy rises to 50%. In summary, income inequality, median household income, and race have a high impact on the crime rate. The median household income and the race could predict the crime rate with an accuracy of about 50%.

Authors: Jiang Zixiao , Feng Zhongyi
Published: April 2021

Since the reform and opening up, China’s economy has been developing, residents’ income has been increasing, people’s health awareness has also been building up, and the health situation has gradually improved. However, with the development of Chinese economy, the problem of income inequality also follows, which has an impact on the health of Chinese residents. In particular, the imbalance of regional economic development and the difference between urban and rural residents’ disposable income inequality have a negative impact on the health of residents, which is not conducive to sustainable economic development and social harmony and stability. This paper analyzes the correlation between regional income inequality and residents’ health status, uses descriptive statistical analysis and principal component analysis to do empirical analysis on the relationship between regional income inequality and residents’ health status, and selects the data from “China Health Statistics Yearbook 2019”. The results of empirical analysis show that regional income inequality has an impact on the health of residents in China. The health level of residents in high-income areas is higher than that in low-income areas. The economic development of the eastern and northern regions is better than that of the central and western regions, and the health status of the residents in the eastern and northern regions is better than that in the central and western regions. In addition, urban-rural income inequality also has an impact on the health of residents. The data show that the health status of urban residents is better than that of rural residents. It can be seen that there is a positive correlation between income level and residents’ health level, and a negative correlation between income inequality and residents’ health level. That is, the higher the income, the higher the health level of residents, the lower the income, the lower the health level of residents; the higher the degree of income inequality, the worse the health status of residents, and it is not conducive to the overall improvement of the health level of residents.

The effects of streptomycin sulfate, carbendazim, penicillin and nystatin on the inhibition of fungi and bacteria in blueberry explants were studied. The results showed that the addition of streptomycin sulfate or penicillin with different concentrations in the medium had a certain inhibitory and killing effect on bacteria in blueberry explant contamination, while the addition of carbendazim or nystatin had a certain inhibitory and killing effect on fungi in blueberry explant contamination. When the concentration of streptomycin sulfate in the medium reached 60units / mL, the highest survival rate was 44.0%, and the bacterial infection rate was the lowest. When the concentration of carbendazim in the medium was 0.4 mg/mL, the survival rate reached 40.5%, and the fungal infection rate decreased greatly. When the penicillin concentration in the medium reached 40mg/mL, the lowest infection rate of bacteria was 4.0%, and the highest survival rate was 31.5%. When the concentration of nystatin in the medium reached 40mg/L, the highest survival rate was 34.5%. Therefore, streptomycin sulfate had better inhibitory effect on bacteria, while carbendazim had better inhibitory effect on fungi, which provided reference for future research.

The development of ethnic sports tourism is conducive to the intergenerational transmission and development of sports culture and the enhancement of “cultural confidence”, as well as the development and utilisation of ethnic sports tourism resources. Based on an analysis of ethnic sports tourism literature in China, this paper first reviews the historical course of ethnic sports tourism research, which can be divided into three stages: exploration, development and improvement. Provincial research locations are analysed at different stages. Secondly, the main content of ethnic sports tourism research is summarised under five headings: definition, resource evaluation, development and utilisation, brand building and marketing management. The research methods used are then analysed. Finally, in order to provide a reference for the in-depth study of ethnic sports tourism in the future, the paper makes four recommendations. These include introducing pluralistic theory, focusing on stakeholders as the subject of research, improving the quantitative evaluation of ethnic sports tourism resources, and exploring the impact of ethnic sports tourism.

Published: April 2021

According to the law of diminishing marginal utility, the marginal utility when consumers purchase a certain product shows a diminishing trend. As a special product, cultural tourism products, whether is the marginal utility produced during consumption also affected by the law of diminishing marginal utility. This paper takes “Impression Liu Sanjie” as the research object and uses a linear regression equation model to study the marginal utility of tourists “Impression Liu Sanjie” cultural tourism products. The results show that the marginal utility produced by tourists buying the cultural tourism products of “Impression Liu Sanjie” shows an obvious decreasing trend. The main reason is that the cultural tourism products of “Impression Liu Sanjie” lack innovation and strong brand characteristics, the overall scale is small, the positioning is not accurate, etc., affected by the competition of homogenized products in the surrounding area, and the return rate of tourists is low. Moreover, there is a gap between existing products and the development trend of high-end tourism, which cannot meet the needs of tourists for indepth experience and research tourism. Therefore, “Impression Liu Sanjie” needs to intensify innovation, fundamentally solve the problem of diminishing marginal utility, further stabilize the source of tourists and meet the needs of tourists for repeated consumption quality, and realize sustainable tourism development.
