Based on the data of China’s Marine engineering equipment industry, in this Paper, the key influencing factors are identified by using Grounded theory and GRNN-DEMATEL method. The study results show the key influencing factors include enterprise’s operational, technical capabilities, enterprise’s social recognition, enterprise’s willingness to cooperate, trust between enterprises, communication and collaboration, opportunism and external environment. Second, enterprise’s operational and technical capabilities are the most important and critical factors, external environment is an irresistible factor. This study enriches and develops the study of supply chain management, and provides theoretical guidance and reference for improving the industry competitiveness.

Li, T.; Han, D.; Ding, Y., and Zhang, L., 2018. The operation evaluation of China's marine industry technology innovation system. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 807–813. Coconut Creek (Florida), ISSN 0749-0208. In order to evaluate the operation efficiency of China's marine industry technology innovation system, the evaluation model is developed by the entropy weighted fuzzy comprehensive evaluation method. Through analyzing the impact factors of marine industry, the evaluation indicators system is constructed, including R&D system; support system; resources input; achievement transformation and overflow ability, using the entropy method to determine the weight and the fuzzy comprehensive evaluation method to analysis effect, the results show that the system performance is good at present, the operational efficiency is still to be improved. The findings accurately present the specific operation performance of China's marine industry technology innovation system, can help researchers precisely find the deficiency of the system, and can provide sufficient basis for the improvement of the measures.

The digital economy is the future of the world in terms of both contemporary trends and opportunities. Developing the digital economy is a practical way of strategically re-thinking network power and digital China and is the only way to achieve successful growth in countries' development economies and seize a commanding position for future development. Tax reductions, which promote high-quality economic development and preserve the overall situation of national governance, are an important measure for all countries to cope with economic pressure. In recent years, China has successively introduced and continuously expanded a series of tax and fee reduction policies that have played an important role in stabilizing its economy and vigorously developing its digital economy. This study consists of six sections. The first section provides an overview of the digital economy, introducing its definitions and connotations as well as the significance of developments of the digital economy. The second section is a literature review of tax and fee reductions; the research results in this field for countries around the world are summarized based on the three perspectives of research objects, tax-reduction-policy effects and research methods and data. The third section describes the impact of tax reductions and fee reductions on China's digital economy from an international perspective. Through the 2019 Forbes Global Top 100 Digital Economy List, this article analyzes the global digital economy corporate structure, observes the positive effects of tax and fee reductions on Chinese digital economy companies and compares the impact of tax cuts and fee reductions on digital economy companies in China, the United States and other countries. Stata software was used to conduct an empirical analysis on the panel data of digital economy companies from both macro and micro perspectives and Analysis of the Effects of Tax and Fee Reduction Policies in the Digital Economy presents an evaluation of the policy effects of tax cuts and fee reductions on digital economy companies from multiple aspects. China does not have a systematic tax and fee reduction policy that is compatible with digital economy development and its investments in large digital economy companies can be increased, as discussed in Problems of Tax and Fee Reduction and Policies in China's Digital Economy. In Policy Recommendations for Tax and Fee Reductions in the Digital Economy, we recommend that China improves and optimizes its tax and fee policies to increase tax incentives for independent innovation and high-level talent.
