说的是 in order to increase the city's tax revenue and economy, the local peopel should help fund the luxury hotel next to the convention center. one of the reason is the visitors purchase a lot goods from the convention center. more out-of-town visitors come, less tax the local people need to pay. 然后又说现在这个hotel只入住50%。 两者win-win game. visitors to the convention center would stay at this hotel to bring more revenue. therefore, the city's tax revenue and economy will increase. 大体就是这个意思
