Curvilinear effect of economic policy uncertainty on innovation in Chinese manufacturing firms: do managerial pay gaps matter?

Abstract

Purpose This study aims to re-examine the impact of economic policy uncertainty (EPU) on firm innovation. Studies on how EPU affects firm innovation have been inconclusive. The authors clarified the curvilinear relationship between EPU and firm innovation and examined the moderating effects of managerial pay gaps, specifically vertical pay disparity and horizontal pay dispersion. Design/methodology/approach This study’s analyses used data collected from Chinese listed companies from 2007 to 2019. Findings The authors found an inverted U-shaped relationship between EPU and firm innovation. Furthermore, vertical pay disparity strengthens the curvilinear relationship, while horizontal pay dispersion weakens it. Practical implications First, politicians should avoid adjusting economic policies too frequently because the high EPU levels created by frequent adjustments can inhibit business innovation. Second, firms should be aware that EPU creates opportunities for leapfrogging. In particular, firms can incentivize executives to take advantage of the valuable growth opportunities presented by EPU by widening vertical pay disparities and avoiding excessive horizontal pay dispersion. Originality/value First, the authors analyze not only the positive effects of lower EPU on firm innovation but also the negative impacts of higher EPU to examine EPU’s “double-edged sword” effect on firm innovation. Second, the investigation of vertical pay disparity and horizontal pay dispersion as moderating variables sheds new light on the equivocal research findings regarding the EPU–firm innovation relationship and clarifies the boundary conditions of the double-edged sword effect of EPU on firm innovation.

A Study on the Impact of Digital Economy Level of RCEP Host Countries on China's OFDI

“…Therefore, this paper refers to the framework construction of scholars such as Qi Junyan [11,12] , and includes fixed telephone coverage, fixed broadband coverage, Internet user ratio, higher education enrolment rate, and mobile phone coverage in the digital economy measurement framework. Unlike existing studies, this paper takes the above digital economy indicators and measures the level of digital economy development in each host country through principal component analysis.…”

How Does Firm-Level Economic Policy Uncertainty Affect Corporate Innovation? Evidence from China

“…As a result, increased economic policy uncertainty can adversely affect a company's financial constraints [48], making it more difficult for them to access funding for innovation investment, which reduces the motivation for enterprise innovation and inhibits the innovation output [18,20,21]. Zhong et al [56] argued that when the government frequently adjusts economic policies, creating high levels of economic policy uncertainty, banks and external investors will demand stringent financing conditions from firms, which significantly increases the financing costs for firms and thus leads to a decrease in their innovation ability.…”
