Abstract:

The China-Central Asia-West Asia economic corridor has the highest resource endowments in the “Belt and Road”. This paper uses principal component analysis to select five factors: market access, logistics and infrastructure, domestic regulatory environment, business environment, and customs management efficiency and 13 secondary indicators to evaluate the trade investment facilitation (TIF) of China-Central Asia-West Asia economic corridor countries. According to the TIF score, the 17 countries along the corridor are divided into four levels: risk zone, caution zone, convenience zone and smooth zone. On this basis, according to the geographical space differentiation of the country along the corridor, the China-Central Asia-West Asia economic corridor is divided into three major corridors, China's corridors belong to the trade and investment cautious zone. The Central Asian country corridor belongs to the transition period of the trade and investment risk zone to the cautious zone. The West Asian country is the mixed corridor divided into three major secondary corridors. The South Caucasus is a trade and investment environment cautious zone, and the West Asian middle country belongs to the risk zone. The countries of the Arabian Peninsula belong to a relatively convenient area. Based on the above, the paper puts forward some suggestions: 1） understand the trade and investment advantages of the convenience zone and the smooth zone countries, and fully use the advantage of them; 2) establish a tiered risk prevention mechanism for trade and investment in the rade and investment risk zones and cautious zones; 3) promote the role of economic organizations in the region such as The Shanghai Cooperation Organization and the China-Arab Forum, and actively support the economic development strategies of countries within the region.

Key words: China-Central Asia-West Asia economic corridor, trade and investment facilitation, corridor, spatial differentiation
