But it has not succeeded in changing the regional disparity in China. In this article, we establish a model factor input called the "lock-in effect" and analyze the channel of the lock-in effect and how it influences the regional economy. On the analyses of thirty provinces’ panel data in China from 1990 to 2005, we find that the lock-in effect of factor inputs further exacerbates the developmental imbalance among regions.展开更多

Instead of using mechanical springs, permanent magnetic locks feature alternating and equidifferent mono and multiple magnetic codes. The locks contain millions of codes. With no key hole or gears, permanent magnetic locks cannot be opened by a master key. The locks are damage proof, shock proof and drill proof, and easy to use. Permanent magnetic locks are used for safes, cars, motorcycles and bicycles.展开更多
