And Performance

Porous membrane materials have the universal use, so it is widely considered as one of the most promising high-tech. Different membranes have different preparation methods. In this paper, the sol-gel method was applied to prepare silica particles using ammonia as catalyst of TEOS hydrolysis, then silica particles were mixed with polyethylene, and finally silica particles were dissolved with hydrofluoric acid, leaving holes, the porous materials were obtained. The results show that: (1) In this experimental conditions, the size of silica particles are closely related to the water content of the system. (2) The size of silica particles affects the agglomeration of particles. The size of silica particles are smaller, the agglomeration is more obvious. (3) As the content of PE increases, the porosity of the samples decreases continuously; in theory, when the content of silica is low, the hole will be greater.

Innovation Impact

How do capabilities-based resources focused on customers, supply chains, and how does innovation impact a firm’s strategic assets and performance? We develop a framework to (1) test strategic resource allocations as investments in future opportunities, (2) examine the influences of strategic resources on strategic assets, and (3) study the effects of strategic assets on performance. The model incorporates data from a 12-year period to examine the lagged effects over a “strategic” length period. The results show that the resources that affect assets include business-to-customer (B2C) marketing expenditures, sourcing attentiveness, inventory readiness, production capacity, and overall innovation creativity. Customer satisfaction and brand equity are two firm-level strategic assets that influence financial performance. The robustness of the overall results was also examined in two technological contexts (low/stable vs. high tech).

Innovation Support

This paper investigates the combined role of innovation support policies and firm's own innovative activities on the performance of Chinese small- and medium-sized enterprises (SMEs) in high-tech sectors. By distinguishing two components of innovative activities—research and development (R&D) investments and embedded innovative capacity—the paper develops and tests an integrative moderated moderation model. The results suggest that in Chinese high-tech SMEs innovation-support policies positively moderate the relationship between R&D investments and performance, but this positive effect diminishes when there are higher levels of embedded innovative capacity. These results highlight that the relationship between government innovation policies and a firm's own R&D investments is not only reciprocal but also more complex than the one so far analyzed in the literature. The results show in particular that the effects of innovation-support policies on R&D investments is not as neat as it seems, because of the internal balance within the firm between investment in R&D and other sources of innovation. Therefore, although innovation support policies have been found to help Chinese SMEs in high-tech sectors benefit from their R&D investments, these policies are particularly effective only when R&D investments are significantly driving firms’ innovative activities. This highlights the relevance of both government support and a firm's own efforts in the competitive modernization of Chinese SMEs.
