with the economic develop还是with the economic development

是
with the economic development
这里的
economic （经济的,经济上的）
是形容词,
修饰 development （发展）
例句：
With the economic development of the region now on a solid footing, the government can turn it's attention to other pressing matters.
因为这个地区的经济发展现在巩固了,政府可以把视野转移到其他紧迫的问题.那将 economic改成economy呢？只能是 with the development of economy吗？如果 economic 改成 economy， 要加冠词 the ：with the development of the economy
