中国投资的空间分布及其对区域经济的影响

The Spatial Distribution of Investment in China and its Influence on the Regional Economy

中国经济30多年的高速发展令世界震惊,投资的不断增加是拉动中国经济发展的主要源泉。投资中最为重要的固定资产投资对中国经济增长起着推动作用,也具有经济发展的指向作用。中国投资具有明显的空间集聚效应,高—高类型区集中分布在京津冀、辽中南和长三角地区。投资飞地在中国很难形成,仅有重庆和兰州。此外,通过空间计量经济学方法和模型以2011年中国地级市(州、盟)级数据为对象,进行实证研究。研究结果表明:空间误差模型比其他模型的分析结果更可靠。国内投资、FDI、土地投入和劳动力投入均是经济增长的显著影响因素,其中,国内投资对区域经济的作用力最大,其次为劳动力投入,最弱为土地投入。

The rapid development of economy 30 years in China shocked the world. The Increase of investment was the main source of economic development. Fixed assets investment as the most important investment played a role in promoting economic growth and was guide to economic development. Investment in China had a significant spatial agglomeration effect. High - high type concentrated in the Beijing - Tianjin - Hebei region, the middle and south Liaoning,the Yangtze River Delta region. The enclave of investment in China was difficult to be formed and was formed only in Chongqing and Lanzhou city. In addition, empirical research was earryed in the prefecture -level cities （prefectures and leagues） in China in 2011 through spatial econometric methods and models. The results showed that： Spatial error model was more reliable than other models. Domestic investment,FDI,land input and la- bor inputs were significant affecting factors of the economic increase. Fixed assets investment was a maximum force of the regional economy, followed by labor input. Land input factors were the weakest influence factor.
