低碳技术清洁化转型的难度和方式与技术活动对不同知识源的依赖模式密切相关,但系统性的依赖模式研究较少。以2006—2019年中国30个省份的空间面板数据为样本,采用空间杜宾模型(spatial Durbin model, SDM)实证检验区域低碳技术创新对本地知识存量、省际知识溢出与国际知识溢出等知识源的依赖模式,并区分清洁与灰色两类低碳技术创新以探究知识依赖模式的可能差异。研究发现:(1)清洁与灰色技术创新的时空特征与路径依赖模式相似,两类创新都具有明显集聚性,以东部沿海地区为核心向外辐射,呈现“东部高,西部低”的特点,且各类知识源对两类创新的作用方向一致。(2)两类技术创新对本地知识存量和国际知识溢出都存在显著的路径依赖,并对前者更为依赖。然而,两类创新又都受到省际知识溢出的显著抑制,使省际知识不能成为创新动能。(3)本地知识存量与国际知识溢出对两类创新的作用具有替代性,表明与两类知识相关的经济活动是竞争资源的排斥关系。可见,围绕低碳技术创新活动,国内外知识与省际间知识之间都存在令人担忧的互为排斥现象,表明低碳技术知识的国内“循环”和国际“循环”都未形成。对此,需要中央到地方的共同努... 相似文献

The low-carbon pilot policy has played an important role when China make efforts to achieve the carbon emission reduction targets. In order to study whether the construction of low-carbon pilot policy can induce enterprises to carry out green technology innovation, this paper uses China′s low-carbon pilot policy as a quasi-natural experiment, constructs a difference-in-difference-in-differences (DDD) model that "before-after the implementation of the low-carbon pilot policy; if or not in the pilot city; if or not belongs to the high carbon emission industry". Since the third batch of low-carbon pilot cities was officially announced in 2017, the duration of the policy is not enough for us to evaluate its effect, so we take the pilot cities announced in 2010 and 2012 as the main research object. The number of enterprises authorized green patents and micro-economic characteristics of listed companies in China from 2006 to 2017 were used to evaluate the effect of the low-carbon pilot policy on enterprises′ green technology innovation, and explore whether the Porter hypothesis based on China′s low-carbon pilot policy is valid.
The results show that: (1) The implementation of the low-carbon pilot policy has significantly improved the green technology innovation level of high-carbon emission enterprises in the pilot cities. The policy has increased the proportion of green patents of high-carbon emission enterprises in the pilot area by 0.929%, and the coefficient is significant at the 5% significance level. Furthermore, the low-carbon pilot policy has a positive effect on both green invention patent and green utility model patent of high-carbon emission enterprises in the pilot area, but has a more significant effect on the green utility model patent. The conclusion of the DDD estimation confirms the validity of the Porter hypothesis based on the low-carbon pilot policy in China.
(2)In order to solve the problem of sample selection bias caused by the difference in initial conditions between the treat group and the control group, this paper introduces the propensity score matching method (PSM), and adopts the propensity score matching-DDD (PSM-DDD) method for the first time to explore the effect of the low-carbon pilot policy on green technological innovation of high carbon emission enterprises within pilot cities. The effectiveness of the matching process is proved through the matching balance test and drawing the propensity score value density function graph. The results of the PSM-DDD are basically similar to those obtained by the DDD method. At the same time, this paper proves the validity of the conclusions through parallel trend hypothesis test and a series of robustness tests.
(3)The analysis of enterprises geographic heterogeneity shows that the low-carbon pilot policy has significantly improved the green technology innovation of high carbon emission enterprises within the pilot cities in the eastern and western regions, but for those in the central region, the low-carbon pilot policy even has a negative inhibitory effect on their green technology innovation. After grouping the data by patent types, we can see that, for green invention patents, the low-carbon pilot policy can significantly promote the green invention patents of high-carbon emission enterprises in the pilot cities in the eastern and western regions, but it has no significant impact on enterprises in the central region; for green utility model patents, the low-carbon pilot policy only has a positive effect on the utility model patents of high-carbon emission enterprises in the pilot cities in the eastern region, but has no significant impact on the green utility model patents of enterprises in the central and western regions.
(4)The analysis of enterprise ownership heterogeneity shows that the low-carbon pilot policy has significantly improved the green technological innovation of non-state-owned high-carbon emission enterprises in the pilot cities, but has no significant impact on the green technology innovation of state-owned enterprises in the pilot cities. Among them, the low-carbon pilot policy has a significant positive effect on promoting both green invention patents and utility model patents of non-state-owned high-carbon emission enterprises in the pilot cities. As for the state-owned high-carbon emission enterprises in the pilot cities, the low-carbon pilot policy only has a positive effect on their green utility model patents, but has no significant impact on green invention patents.
The results of this paper further expand the study on the Porter hypothesis and the evaluation of the low-carbon pilot policy. 相似文献

考察技术创新与权益资本成本的关系,实证研究发现,企业的权益资本成本随时间的推移在企业各生命周期有不同的变化趋势:在成长期呈下降趋势,在成熟期和衰退期呈上升趋势;技术创新投入初期,信息不对称的降低导致权益资本成本降低,而后期其所带来的产出则会导致权益资本成本上升,即技术创新与权益资本成本之间呈现U型关系;企业在各生命周期阶段具有不同的财务与组织特征,技术创新对权益资本成本在成长期和成熟期具有负向的影响,在衰退期具有正向的影响。 相似文献
