生态退化制约着中国经济可持续发展,投资生态资本能否促进长期经济增长仍是一个悬而未决的重要理论命题。为此,在一个增广MRW模型框架下,分析生态资本、人力资本与长期经济增长的内在理论逻辑;进一步,构建多维度生态资本指标体系,借助2004-2013年中国省际面板数据,对生态资本的经济增长效应进行静态和动态分析。研究结果表明:生态资本能够促进长期经济增长;人力资本积累与外溢是生态资本产生经济增长效应的主要作用机制,生态资本的经济增长效应主要通过生态资本的外部性特征得以实现。对应的政策含义是,加大对生态资本投资,并进一步提高人力资本水平,以促进生态资本转化为生产力。
Ecological degradation restricts the sustainable development of China’s economy and whether investment in ecological capital can promote long-term economic growth remains an important theoretical proposition that remains unresolved. Therefore, under the framework of an augmented MRW model, the internal theoretical logic of ecological capital, human capital and long-term economic growth is analyzed. Furthermore, a multi-dimensional index system of eco-capital is constructed. Based on the panel data of China’s provinces from 2004 to 2013, The economic growth effect of capital is analyzed statically and dynamically. The results show that: ecological capital can promote long-term economic growth; human capital accumulation and spillover are the main mechanism of the economic growth effect of ecological capital; the economic growth effect of ecological capital is mainly achieved through the external characteristics of ecological capital. Corresponding policy meaning is to increase investment in ecological capital, and further improve the level of human capital in order to promote the ecological capital into productive forces.
