供应链特征对企业绿色创新的影响——基于资源协同与挤占视角的分析

Impact of supply chain characteristics on firms'green innovation:An analysis based on resource synergy and crowding-out perspectives

在供应链竞争背景下,其特征对企业绿色创新有何影响?本文基于重污染行业上市公司的供应链数据,借助固定效应模型实证检验了供应商(客户)集中度对其绿色创新的影响。研究发现:重污染企业的供应商(客户)集中度不利于企业的绿色创新,产生了“资源挤占”效应,而非“资源协同”效应,这一结论在考虑各种稳健性检验后依然成立。机制分析发现,内部激励可以削弱(强化)供应商(客户)集中度对企业开展绿色创新活动的不利影响;外部压力仅加剧了供应商集中度对企业开展绿色创新活动的不利影响。异质性分析发现,供应商集中度不利于开展绿色创新活动主要体现在非国有企业和财务资源较强的企业,客户集中度的不利影响主要体现在国有企业、议价能力较低和财务资源较弱的企业,而供应商(客户)集中度对议价能力较强和吸收能力较强企业的绿色创新没有显著影响。本文从供应链特征视角贡献于绿色创新相关研究,也为企业如何合理选择供应链关系提供了一些参考。

In the context of supply chain competition,how its characteristics affect firms'green innovation is a topic which aroused hot discussion among the academia.Based on the supply chain data of listed companies in the heavy pollution industry,this paper empirically examined the impact of supplier(customer)concentration on green innovation with the help of fixed effect model.The study found that the concentration of supplier(customer)in heavily polluting enterprises is not conducive to green innovation,resulting in a"resource crowding-out"effect rather than a"resource synergy"effect,which is still valid after considering various robustness tests.The mechanism analysis found that internal incentives can weaken(reinforce)the negative impact of supplier(customer)concentration on firms'green innovation,while external pressure only exacerbates the negative impact of supplier concentration on firms'green innovation.The heterogeneity analysis found that the adverse effect of supplier concentration on green innovation is mainly found in non-state-owned enterprises and enterprises with stronger financial resources,the adverse effect of customer concentration is mainly found in state-owned enterprises and enterprises with lower bargaining power or weaker financial resources,while supplier(customer)concentration has no significant impact on green innovation in firms with stronger bargaining power or stronger absorptive capacity.This paper will invariably contribute to the research on green innovation from the perspective of supply chain characteristics,and it will also provide some references for enterprises on how to reasonably choose supply chain relationships.
