摘要:The essay tends to focus on the investigation into the changing sustainable development trend. It is important to know which areas have seen the greatest progress and which areas have stalled or even regressed around the globe. The researchers will compare and combine the modernization theory and dependency theory to figure out the potential factors which result in the different levels of achievement between all the 17 sustainable development goals (SDG). The researcher team are more likely to adopt both qualitative method and quantitative method to ensure the accuracy of the conclusion. In addition, due to the fact that the primary data related to this topic is too broad to obtain, the scientific group will mostly employ secondary data from the United Nations to carry out the research. Most of the data in the essay are from various United Nations documents and reports to ensure the authenticity and objectivity of the data. It allows the researchers to pay more attention on the specific analysis. Lastly, the goal of this paper is to find out the basic laws of sustainable development by looking for the unique representative parts of the 17 SDG goals (Basic education, Food safety, Life below water, etc.) and analysing their development trends in the past few years. In addition, the researchers tend to work out suggestions and solutions to those problems.
