High-Speed Railway and the M&A Behavior
High-speed railway (HSR) shortens the spatial and temporal distance between regions and has a profound impact on regional economy and enterprise decision-making. The opening of HSR promotes the M&A activities of listed companies, and the opening of non-intercity HSR has a more obvious effect on the promotion of M&A decisions of enterprises.

High-Quality Tourism Destinations Based on Spatiotemporal Big Data
A tourism destination is a region where tourist activities take place; this can be either a special tourist site or any area in a city where tourist activities occur. It is one of the most important parts of the entire tourism process. Creating high-quality tourism destinations can provide tourists with high-quality experiences and improve the overall living environments in an area, thereby pleasing locals and attracting visitors from far and wide.

High-Quality Gastronomy for Tourism Offer
Food has evolved from a basic necessity to a primary motivation for travel. While providing a high-quality gastronomic offer is still a restaurant’s primary function, quality is no longer enough; today’s demanding guests seek unique and memorable dining experiences. A restaurant’s competences play a significant role in shaping the guests’ overall perception of the quality and derived perceived value, both of which ultimately impact the competitiveness of both the restaurant and the gastronomic destination.

Heterogeneity of Corporate Financialization and Total Factor Productivity
The most important stylized fact about the Chinese economy is the tendency toward financialization, which is referred to as a key feature of capital extension following the reversal of the real economy. Corporate financialization can be defined as a firm making substantial investments in financial assets. Some empirical research provides evidence that corporate financialization can stimulate the short-term performance of firms and reach higher production efficiency yields, while over-financialization may hinder economic growth by extracting additional profits from the economy into the financial sector, thereby reducing production efficiency. The capital misallocation causes poor allocation of resources, leading to a negative effect on aggregate total factor productivity (TFP).

Heritage and Artificial Neural Networks
The classification of the United Nations Educational, Scientific, and Cultural Organization (UNESCO) World Heritage Sites (WHS) is essential for promoting sustainable tourism and ensuring the long-term conservation of cultural and natural heritage sites. Therefore, two commonly used techniques for classification problems, multilayer perceptron (MLP) and radial basis function (RBF) neural networks, were utilized to define the pros and cons of their applications.

Herfindahl–Hirschman Index
The Herfindahl index (also known as Herfindahl–Hirschman Index, HHI, or sometimes HHI-score) is a measure of the size of firms in relation to the industry they are in and an indicator of the amount of competition among them. Named after economists Orris C. Herfindahl and Albert O. Hirschman, it is an economic concept widely applied in competition law, antitrust and also technology management. HHI is calculated by squaring the market share of each competing firm in the industry and then summing the resulting numbers,(sometimes limited to the 50 largest firms), where the market shares are expressed as fractions or points. The result is proportional to the average market share, weighted by market share. As such, it can range from 0 to 1.0, moving from a huge number of very small firms to a single monopolistic producer. Increases in the Herfindahl index generally indicate a decrease in competition and an increase of market power, whereas decreases indicate the opposite. Alternatively, if whole percentages are used, the index ranges from 0 to 10,000 "points". For example, an index of .25 is the same as 2,500 points. The major benefit of the Herfindahl index in relationship to such measures as the concentration ratio is that it gives more weight to larger firms. Other benefits of the Herfindahl index includes its simple calculation method and the small amount of easily obtainable data required for the calculation. The measure is essentially equivalent to the Simpson diversity index, which is a diversity index used in ecology; the inverse participation ratio (IPR) in physics; and the effective number of parties index in politics.

Named after economists Orris C. Herfindahl and Albert O. Hirschman, it is an economic concept widely applied in competition law, antitrust and also technology management. It is defined as the sum of the squares of the market shares of the firms within the industry (sometimes limited to the 50 largest firms), where the market shares are expressed as fractions.

HEIs, Latin America Circular Economy
HEIs (Higher Education Institutions ) are main actors in the economic development and innovative potential of regions, but now and an increasing number of additional roles are expected. HEIs, as institutional actors, are enablers of social, economic, and cultural development, and sustainability. HEIs can foster collaboration between actors and catalyze public awareness and engagement in CE practices.

Healthcare Employees’ Pro-Environmental Behavior for De-Carbonization
Buildings worldwide use a large amount of energy and, hence, contribute to increasing the level of greenhouse gases emission (GHG). It was realized that most electrical energy is used in buildings for heating, cooling, and ventilation purposes.
