This study aims to explore why marine development and maritime security in Pakistan are significant and what the Chinese concerns are. Therefore, the objective of this research is to analyse a growing Pak–China bilateral interests, particularly at Gwadar, to achieve the geostrategic objectives of China–Pakistan Economic Corridor (CPEC).

The study adopts a qualitative means to discuss the significance of China’s ambitions towards the CPEC project concerning strategic deep-sea management and maritime regulations in the region, with a particular focus on the Gwadar Port.

The paper concludes that the Gwadar Port is a critical element for maritime security in the whole region. The study also provides an analysis of national and international, security and legal challenges associated with CPEC.

Most of the potential outcomes have already been discussed in public, though a limited academic discussion is available on the legal aspects. It is particularly so with regard to the development and capacity building in the maritime sector of Pakistan under this project. This study aims to explore why marine development and maritime security in Pakistan is significant and what the Chinese concerns are.

Human-induced changes in climate have affected the environment to the extent that any more economic development at the cost of the environment will be too costly. Thus, sustainable development options posing no additional harm to the environment are the only viable option. This study aims to examine the likely environmental impacts of infrastructural developments through the China–Pakistan Economic Corridor (CPEC).

There is a scarcity of academic debate and discussion on the environmental impact of CPEC developments in laws and policies on the environment. The qualitative approach is followed in this study and official documents and reports are used to investigate the environmental challenges posed by CPEC.

The findings show three possible environmental concerns which could increase the climate change vulnerability of Pakistan. The coal-fired power plants are the most prominent threat based on their CO₂ contributions and smog. Second, cutting more than 54,000 trees for roads infrastructure will increase CO₂ concentration along the CPEC route. Third, increasing vehicle trafficking by up to 7,000 trucks per day on Karakorum Highway alone will release 36.5 million tons of additional CO₂.

It is essential to rethink the environmental cost of CPEC. The study suggests economic and legal cooperation between Pakistan and China as a way forward to deal with climate change issues. Environmental laws should be a vital part of CPEC projects to ensure their safety, security and sustainability.

By combining geopolitical and economic factors and from a geoeconomic perspective, the importance of Gwadar to China and Pakistan is discussed in detail. By applying geoeconomic approach and based on the historical approach, geographical and geopolitical conditions and international development trends of Gwadar port, the authors develop the analytical framework to analyze the Gwadar port and studied its importance in the development of China and Pakistan, as well as the positive influence on the economic growth of both countries.

A geoeconomic study is done to run a more profound and more comprehensive analysis of China–Pakistan economic relationship, as geoeconomic includes interrelations of geographical, geopolitical and economic factors in international relations.

The results show that Gwadar Port's development could enhance the economic security of both China and Pakistan. With the opening of Gwadar Port, oil and energy in the Middle East will be imported directly to China through Pakistan's oil pipeline. This is not only oil but also goods from Central Asia, and even Europe and the USA will land from Gwadar Port and enter China through the China–Pakistan Economic Corridor (CPEC). The development of Gwadar port under the CPEC program could also dramatically increase the capacity of Pakistan's maritime trade while reducing its dependence on the current largest port, Karachi, near the India border.

Geo-economics theory is used to run a more profound and more comprehensive analysis of China–Pakistan economic relationship as geoeconomic includes interrelations of geographical, location, geopolitical and economic factors in international relations. By combining geopolitical and economic factors and from a geoeconomic perspective, this study seeks to analyze the Gwadar port development and its implications for both China and Pakistan.

Technology parks (TPs) are used as a tool to improve economic outlook of the region through innovation generation. This study aims to evaluate the perception of tenants of TPs to determine the gap in the expectation and identify types of firms preferring to locate in a TP.

This is the first study in Pakistan to collect data about perceived benefits of TPs in Pakistan from the decision-makers of 110 tenant firms. The cluster analysis and lift ratios are used to draw statistical inferences.

The firms can be classified into three clusters – commercial-orientation firms, science and technology-oriented firms and young tech firms – with distinct needs for survival and growth in a TP. Moreover, TPs should not just be treated as property projects for providing support services, also knowledge sharing, training and development opportunities and proximity to hubs of knowledge and markets is vital to attract a variety of industry.

Academia and policymakers have been equally interested in the potential impacts of these innovation hubs. However, there have been lack of empirical evidence on how and what to offer the incumbents of these TPs. The government of Pakistan is trying to build more TPs for promoting business activities under CPEC. Therefore, it is extremely important to determine the needs of tenants of TPs for successful utilization of huge amount of public money to be invested in TPs.

Porous silicon (Si) was fabricated by using three different wet etching methods, namely, direct current photo-assisted electrochemical (DCPEC), alternating CPEC (ACPEC) and two-step ACPEC etching. This study aims to investigate the structural properties of porous structures formed by using these etching methods and to identify which etching method works best.

Si n(100) was used to fabricate porous Si using three different etching methods (DCPEC, ACPEC and two-step ACPEC). All the samples were etched with the same current density and etching duration. The samples were etched by using hydrofluoric acid-based electrolytes under the illumination of an incandescent lamp.

Field emission scanning electron microscopy (FESEM) images showed that porous Si etched using the two-step ACPEC method has a higher porosity and density than porous Si etched using DCPEC and ACPEC. The atomic force microscopy results supported the FESEM results showing that porous Si etched using the two-step ACPEC method has the highest surface roughness relative to the samples produced using the other two methods. High resolution X-ray diffraction revealed that porous Si produced through two-step ACPEC has the highest peak intensity out of the three porous Si samples suggesting an improvement in pore uniformity with a better crystalline quality.

Two-step ACPEC method is a fairly new etching method and many of its fundamental properties are yet to be established. This work presents a comparison of the effect of these three different etching methods on the structural properties of Si. The results obtained indicated that the two-step ACPEC method produced an etched sample with a higher porosity, pore density, surface roughness, improvement in uniformity of pores and better crystalline quality than the other etching methods.

The study performs an empirical test to assess the impact of the Pakistan-China Free trade agreement (FTA) on Pakistan, China, and the World's exports under homogenous and differentiated products. This study employs the modeling with Poisson specification with Poisson Pseudo-Maximum Likelihood method for the estimations. The results of empirical test show that the effect of FTA on the FTA and Non-FTA countries is greater in the differentiated product as compared to the homogenous product. Therefore, one of the most important policy implications provided by this study is that export enterprises need to concentrate on differentiated products as compare to the homogenous products after the implementation of the Pakistan-China FTA. Moreover, the previous literature concluded that Pakistan-China FTA was more beneficial for China as compared to Pakistan. However, according to this study, if Pakistani enterprises focus more on differentiated products as compared to homogenous products, then it will be equally beneficial for both Chinese and Pakistani enterprises. This study will contribute to the literature by considering the Bertrand competition between asymmetric countries and find out the effect of the FTA on these three countries. It considers China, Pakistan, and the Rest of the World as first, second, and third countries.
