改革开放以来，西部资本要素外流严重，延缓了该地区的经济增长速度，是导致东西差距逐步拉大的一个不可忽视的因素。本文认为，应把稳住西部资本要素作为研究西部大开发的切入点，并提出了稳住西部资本要素的政策建议──优化西部投资开发环境和加大国家宏观经济政策倾斜等项措施。 Since the reform and opening up, the capital outflow in western China has seriously delayed the economic growth in the region, which is a factor that can not be neglected to widen the gap between the east and the west. This paper argues that stabilizing the western capital should be taken as the starting point to study the development of the western region and put forward some policy recommendations to stabilize the western capital: optimizing the investment and development environment in the western region and stepping up the national macroeconomic policies.
