Although there is a general recognition that human resource management (HRM) practices are a key factor in a firm’s innovation performance, from the extant literature we see that empirical investigation does not always offer evidence to support this assertion. This paper proposes that knowledge transfer positively moderates the link between HRM practices and firm innovative performance in foreign multinational enterprises (MNEs) subsidiaries operating in China. Specifically, a tacit knowledge approach affects knowledge transfer in HRM practice as well as firm innovative performance. With hierarchical linear modeling, our results demonstrate that: (1) HRM practices can have a positive effect on firm innovative performance; (2) knowledge transfer can positively moderate the effects of HRM practices and firm innovative performance; and (3) the positive effects of knowledge received on HRM practices and firm innovative performance will be strengthened with a tacit knowledge approach. This paper shows that through the adaptation and application of a tacit knowledge approach, executives can create an atmosphere for interaction between the workforce and senior colleagues, forming an inter-intra network chain to share intangible knowledge that is mostly derived from the culture and experience.

PurposeAs an important driving factor of digital innovation, distributed innovation has received extensive attention from academia and business circles in recent years. However, extant works lack a discussion on the influence of distributed innovation on digital innovation performance. Drawing on the opportunity perspective, the study constructs a moderated mediating model to address how distributed innovation directly affects enterprises' digital innovation performance. Particularly, it investigates the moderating and mediating effects of IT-enabled capabilities and digital entrepreneurial opportunities on the above correlation.Design/methodology/approachWith a survey data set of 399 Chinese science and technology enterprises, the study conducts hierarchical linear modeling (HLM) and bootstrap to test the study’s hypotheses.FindingsResults demonstrate that (1) distributed innovation positively enhances enterprises' digital innovation performance; (2) digital entrepreneurial opportunities partially mediate the positive relationship between distributed innovation and digital innovation performance; (3) IT-enabled capabilities positively moderate the relationship between distributed innovation and digital entrepreneurial opportunities; (4) IT-enabled capabilities positively moderate the mediating role of digital entrepreneurial opportunities in the relationship between distributed innovation and digital innovation performance.Originality/valueThis is an empirical study on the impact mechanism of IT-enabled capabilities and digital entrepreneurial opportunities on the relationship between distributed innovation and digital innovation performance in China. It advances theories related to distributed innovation, digital innovation and digital entrepreneurial opportunities, and provides decision-making references for the enhancement of digital innovation capabilities of science and technology enterprises.

Purpose Drawing on the resource-based view, institutional logic and isomorphic pressure theories, this study constructed a theoretical model to explore the correlations between government subsidies and innovation performance. Particularly, this study aims to investigate the moderating effects of ownership types and degree of internationalization on these relationships. Design/methodology/approach To empirically test the relationships, the authors use panel data from high-tech manufacturing and automobile manufacturing industries in Chinese A stock listed companies for the period 2011–2015 and performed regression analysis. Findings Results indicate that government subsidies positively enhance enterprises’ innovation performance; there is a big gap between government subsidies’ incentive effect on innovation performance between state-owned enterprises (SOEs) and private-owned enterprises (POEs); with the improvement of internationalization, the promotion effect of government subsidies on enterprise innovation performance is strengthened; there is a three-way interaction between government subsidies, degree of internationalization and ownership types, such that in the presence of a low degree of internationalization, there is a big gap in the incentive effect of government subsidies on the innovation performance of SOEs and POEs; in the presence of a high degree of internationalization, the gap is significantly reduced. Originality/value This is an empirical study on the impact mechanism of ownership types and internationalization on the relationship between government subsidies and innovation performance in China. It provides valuable insights to show how internationalization can dramatically improve SOEs’ efficiency disadvantages in the allocation of government subsidies to innovation activities.

As a new and effective testing cite for electromagnetic compatibility test, the reverberation chamber, especially a newly built one, must verifyits field uniformity. So,when undertaking a study on a reverberation chamber, its field uniformity is a key indicator. This article, in accordance with the actual dimension of a reverberation chamber, built an FEKO model, and calculated the electric field of the 8 vertices of the workspace, then verified the field uniformity of this reverberation chamber meet the IEC 61000-4-21 standard.

A novel KF‐modified nanorod support Zr−Ce oxide as an efficient solid base catalyst was prepared. XRD, FT‐IR, CO2‐TPD, TEM‐EDS, and Raman were employed for the catalyst characterization. The results showed that the appropriate activation temperature could facilitate the insertion of K+ into the vacancy sites of the ZrO2−CeO2 nanorod support, and some new strong basic active sites of K3Zr2F11, KCe2F9, Ce2Zr2O7 were generated with the addition of KF on the mixed ZrO2−CeO2 support. The prepared KF/ZrO2−CeO2 as a solid base catalyst exhibited high activity and stability for transesterification of soybean oil with methanol to biodiesel. The high biodiesel yield of 99.8 % was obtained under the following conditions: 15 wt % KF loading amount, calcination temperature 400 °C, molar ratio of methanol/oil 20 : 1, 5 wt % catalyst account (wt/wt oil), reaction time 5 h at 65 °C. The formation of basic active sites of the KF/ZrO2−CeO2 catalyst and the mechanism for the catalytic reaction were explored.
