With the rapid development of high quality industries, it is particularly important to study the sustainable competitiveness of manufacturing and its driving factors. The aim of this paper is to build the whole competitiveness index to analyze the recent development trends of manufacturing in G20 participating countries from 2008 to 2018. Meanwhile, based on the diamond theory, this paper adopted a panel regression model to conduct an empirical analysis on various factors that affect the sustainable competitiveness of manufacturing. These results showed the following: (1) Transport services have the most significant effect on manufacturing in developing countries. (2) Intellectual property only has a positive and significant effect on manufacturing in developed countries. (3) Information technology plays a significant role in all countries, but it is more effective in developed countries. Finally, this paper puts forward some suggestions for the sustainable development of manufacturing.

This study aims to analyze the factor affecting the urban industry development in Guangzhou. Based on push-pull-mooring theory, we explain the reasons for choosing the above indicators and use order parameters to analyze their impact on the urban industrial development. The results show that: (1) Environment has an obvious promoting effect on the urban industrial development. This shows that the current environment and the urban industrial development have reached a balance. (2) Technology has a positive impact on the urban industrial development, but it needs to go through the technology running in period smoothly. (3) Different from other factors, finance has a crowding out effect on industrial development. However, the development of finance will promote the rapid development of industry in Guangzhou. (4) The impact of finance, technology and green on UID is applicable to different development stages of UID, that is, these variables are related. Lastly, we provided development suggestions for Guangzhou. This will lay a foundation for promoting its industry.
