Venture capital is an important force in promoting technological innovation and social progress. Research regarding the attention on venture capital can help understand the development and social influence of venture capital, which is conducive to the policy guidance and incentive to the industry. With the rapid development of information technology, the Internet has become the main source and dissemination channel of information, and search engines have become an important interface for information. Through a deep analysis of the search index of venture capital, we can find information that is more important. Based on the principle of time series visualization, we have transformed the time series data of attention on venture capital into complex networks and analyzed its network characteristics. We collected the Baidu index of Chinese venture capital from January 1, 2018 to November 25, 2019 and constructed a time series network based on PC plus mobile search, PC search, and mobile search. The results show that the convenience of the mobile terminal offers makes it the primary mode of tracking the industrial dynamics of venture capital, especially hot news. Relatively, PC terminal search is more stable than mobile search, more focused on industry reports, and refers to long-term followers of venture capital. Both degree distribution and centrality distribution of the three networks show that abnormal peaks and lows are few and the number of key time points in the time series of search on venture capital is insignificant. However, the clustering results show obvious segmentation effect that the peak effect of hot news is evident.

As the subject of pollutant emissions, enterprises play an important role in environmental governance and should consciously fulfil their environmental responsibility. So, can the enterprise perform environmental responsibility to increase their investment in research and development (R&D)? Based on the data from China’s Shanghai and Shenzhen A-share listed enterprises in 2011–2019, this paper explores the relationship between corporate environmental responsibility and R&D investment and examines the dual moderating effects of public attention and intellectual property protection. It is found that the implementation of corporate environmental responsibility can promote R&D investment. Public attention moderates the positive relationship between corporate environmental responsibility and R&D investment; it seeks that the positive relationship becomes higher with public attention. With higher regional intellectual property protection levels, the moderating effect of public attention on corporate environmental responsibility and R&D investment will be more obviously higher. This research provides theoretical support for enterprises to fulfil their environmental responsibilities and a new perspective for revealing the factors of enterprises’ R&D investment, which can offer a foundation for future research and practices.
