摘要:中国改革开放以来,政府公共投资一直是推动区域经济发展的强大动力,而政府公共投资在社会总投资中也一直占有较高的比例。运用柯布-道格拉斯生产函数对广西省和广东省经济增长和政府公共投资的关系进行回归分析,揭示公共投资与地方经济增长的关系。通过对比两地之间政府公共投资的产出弹性之间的差距,发现相比于广东省,广西省在公共投资的利用方面还有很大的差距。因此,要在加大对以广西为代表的西部地区公共投资的规模、确保范围合理的同时,当地政府也要做好相应的承接工作,积极利用公共投资培养管理人员和技术工人,完善相关产业链条。
Abstract: Since China's reform and opening up, government public investment has always been a powerful driving force for regional economic development, and government public investment has always held a high proportion in total social investment. Using the Cobb-Douglas production function, a regression analysis of the relationship between economic growth and government investment in Guangxi and Guangdong Province reveals the relationship between public investment and local economic growth. By comparing the gap between the output elasticity of government public investment between the two places, it is found that there is still a large gap between the use of public investment in Guangxi Province compared to Guangdong Province. Therefore, while increasing the scale and ensuring the scope of public investment in the western region represented by Guangxi, the local government must also do a good job in carrying out the work and actively use public investment to train managers and skilled workers to improve the relevant industrial chain.

在供给侧改革的大背景下,供给越来越受到人们的重视,作为需求的三驾马车之一的投资得到的重视越来越少。但是供给侧的改革也不是意味着就要忽略需求侧的刺激,温和供给学派也有强调储蓄与投资。供给侧改革着力点在机构性,最终的目的是解放生产力,因此供给侧的改革是要有一个相当长周期的。我们要知道,供给侧的改革不是万能的,同时需求侧的改革也不能放松,“三驾马车”必须继续前行。
随中国经济增长进入新常态,中国东部发达地区的经济增长已经放缓,产能已经出现过剩的现象。国家开始加大对中国中西部地区,尤其是西部地区的投资,用以促进西部贫困地区的经济发展。……
