通过考察黑龙江省公共投资的增长效应和环境效应,得到结论:目前黑龙江省的公共投资是低速增长、轻度污染类型的。为了实现经济增长和环境持续的双重目标,即实现绿色经济增长,应当向高速增长、轻度污染类型的公共投资结构转变。这要求,减少在基础设施上的公共投资,增加在教育科技领域和污染治理方面的公共投资。 By examining the growth effects and environmental effects of public investment in Heilongjiang Province, it is concluded that at present, public investment in Heilongjiang Province is of low growth rate and mild pollution. In order to achieve the dual goals of economic growth and environmental sustainability, that is, to achieve green economic growth, we should shift to a structure of public investment that is characterized by rapid growth and mild pollution. This requires reducing public investment in infrastructure and increasing public investment in education, science and technology and pollution control.
