Trade vulnerability assessment in the grain-importing countries: A case study of China.

Since the 2008 global food crisis, food security vulnerability has been a prominent topic in the food policy debate. However, vulnerability is inherently difficult to conceptualize and is more challenging to operationalize and measure. This study constructs a mathematical model and takes China as a...

However, vulnerability is inherently difficult to conceptualize and is more challenging to operationalize and measure.
