The huge flow of foreign direct investment (FDI) in recent decades has prompted concern among policy-makers and researchers regarding its impact on the environment, as well as its contribution to China’s economic growth. In this study, by combining FDI and trade pollution theory, we establish a model to evaluate the impact of FDI on pollution, which facilitates testing the “pollution haven” hypothesis. Our results indicate that FDI is concentrated in pollution-intense industries. Moreover, it is necessary to undertake further research on FDI pollution with new data after environmental regulation.

We compare environmental impacts associated with incoming foreign direct investment versus domestic capital in China. We use aggregate data on Chinese provinces’ economic and pollution indicators to explore the effects of the financial origin of fixed capital. Our simultaneous models consider three prime channels through which these effects work: economic scale, sectoral composition, and pollution intensity. Results show that emissions associated with foreign financed capital are lower than with domestically financed capital for some but not all of the considered types of pollution.

Accompanying the development of economy, multinational enterprises (MNEs), as a role of promoting economic development, may also lead to environmental pollution of host countries. China has become one of the most significant countries in terms of introducing foreign direct investment (FDI), along with which the pollution problem has become serious. Whether the MNEs affect the environment and whether the MNEs in China perform worse than local enterprises attracts more attention. To understand more about it, we creatively build a model of vertical product differentiation, and the result indicates that the environmental performance of MNEs is better than that of local enterprises.

After three decades of reform and opening up, China’s economy has experienced huge changes. Against the background of economic globalization, foreign direct investment (FDI) plays an important role in China’s economy. China has become one of the world’s largest FDI inflow countries, which has had an important impact on its economic development. FDI has preferred the industrial sector, which also has serious environmental pollution. This study will consider vertical and horizontal FDI location choice theory and conduct theoretical analysis concerning the FDI location choice within the industrial sectors, as well as empirical analysis to test the distribution of FDI in pollution-intense industries. Furthermore, the “Catalog of Industries for Foreign Investment” is one of China’s important industrial policies to guide foreign investment. Since being implemented in 1995, it has made five adjustments. The analysis of the distribution of FDI in the polluting industries and the impact of the change process will provide advice instructive for the government to amend the catalog.

Accompany with the development of economy, the environment becomes deteriorating, especially in developing countries. Many studies found that foreign direct investment (FDI) with the effect of technology spillover would be one of the best ways to solve the environmental problem. By using the model of trade theory distinguishing between environmental and productive technology and separately analyzing the technology spillover effect of these two technologies on reducing environmental pollution in host countries, we find that the pollution problem could be worse if more intensive pollution industrial structure is induced by the environmental technology development. Naturally, this did not mean restraining the development of technology, but rather emphasizing the importance of the regulation and the industrial structure.

Porous titanium is used in many bioimplant and electrode applications because of its interconnected pore structure and good corrosion resistance. The purpose of this paper is to study the anodic polarization behavior of porous titanium in different electrolytes and clarify the influences of the porosity and macro‐pore size on the corrosion resistance.

The porous titanium with 10‐70% porosities and average macro‐pore sizes in the range of 100‐500 μm was prepared by the powder metallurgy method using polymethyl methacrylate (PMMA) as a space holder. Electrochemical corrosion tests were performed on porous titanium as well as solid titanium (with the same irregular and isolated micro‐pore structures as that on the interconnected spheroidal macro‐pore walls of porous titanium) in the 0.1 M H₂SO₄, 1 M NaOH and 0.9% NaCl (37 °C) solutions.

It was found that porous titanium exhibited an active‐passive transition behavior in the 1 M NaOH and 0.1 M H₂SO₄ solutions. In contrast, a self‐passivation transition behavior was observed in the 0.9% NaCl solution (37 °C).

The paper demonstrates that both the porosity and macro‐pore size of porous titanium play an important role in determining the corrosion rate, rather than the corrosion potential.
