Basically, "多印钱,多补贴,多放货款,让大家多买东西。就差没喊出这样的口号了:我们要为GDP活着!"means "To print more money, release more subsides, grant more loans, and encourage people to purchase. We almost called it out as a slogen that 'We must live for the growth of GDP!'
The first question you asked is economic related. "多放贷款“ means grant more loans. If more loans are granted, then people will be holding more cash on hands and their incentive of purchasing will rise. Once the market sense the purchasing power of consumer increases, the price would be adjusted. In this case, it would be brought up. So, in this case, yes. '多放贷款‘could indirectly cause '物价飞涨’。
For the second question, please see the translate on top.
Hope it's helpful ^^
