In this paper, two widely adopted subsidy strategies, i.e., subsidy for facility investment and subsidy for the price of shore power, are analytically discussed and compared in the Stackelberg game framework.

Because the total subsidy cost had a significant impact on the carbon reduction of the Guangzhou Port container collection and distribution network under different subsidy
Finally, we use numerical simulations to study the effects of government subsidies and supply chain contracts on decisions to use shore power to reduce emissions during port
Second, government-led exploration is necessary after upgrading the emission reduction equipment for ports and shipping companies. The subsidy of ports and shipping
Encouraging shipping companies to use shore power has become an important issue in green port construction. This paper builds a Nash game between two shipping companies regarding
Simulations are conducted in Matlab to explore the evolution of strategic choices for promoting shore power and evaluate the impact of various factors on ships'' shore power choices.

This paper focuses on the problem of government subsidy structure to ports. The aim of this research is to propose a framework of optimizing government subsidy structure to
We, therefore, examine the optimal subsidy design for government-operated ports, aiming at balancing the environmental benefits and subsidy expenses. Considering the
This chart ranks the companies which have received the most American taxpayer support (in the form of government subsidies) since the year 2000. Government subsidies take a variety of forms: tax credits, abatements,
First, as long as at least one shipping company uses shore power, the optimal decision of the two shipping companies on the sale of container capacity would be affected by

A lack of coherent policy and disparity in subsidies have led to a vast difference in the per unit price of electricity at shore power facilities on Chinese ports. Ports that have government funds at their disposal, such as
The government is considering financial support for local manufacture of shipping containers amid growing shortage and rising costs post Covid. Direct subsidy and support via
Without subsidies, this might cost ₹1.5–2 lakh. With government support, you could save nearly ₹60,000–80,000 upfront. Add in savings of ₹2,000–3,000 per month on electricity bills, and you''ve got a system that pays

Firstly, ship visa and container truck trajectory data are used to develop queuing models for container trucks and ships at ports or ship locks. Then, a bi-level programming
The government subsidy function implements a corresponding subsidy or penalty strategy according to the scale of port shore power construction and ship shore power cost. When the cost of port shore power construction or container ship power consumption is higher than a given value, the government will provide a specific cost subsidy.
For shipping companies, energy such as low-sulfur fuels and liquefied natural gas has become an essential supplementary means to meet emission reduction requirements. This research considers the impact of government subsidies on port shore power construction and ship shore power use.
Due to the absence of government subsidy, the game between the government and the port does not exist in this case. Therefore, the port can independently determine the investment scale of shore power facilities and the price of shore power service to maximize its own net profit.
Specifically, when T 1 <T <T 1s, the two shipping companies reach multiple equilibria where only one uses shore power if there is no government subsidy; moreover, the emergence of a government subsidy enables them to reach an equilibrium where both use shore power.
In addition, through government subsidies, effectively alleviating the operational pressure of port companies and shipping companies can stimulate port companies and shipping companies to participate in the construction of green ports .
Two common subsidy strategies are considered and compared, namely, subsidy for the investment of shore power facilities and subsidy for the usage of shore power. In addition, the effects of port operation schemes (i.e., private operation scheme and public operation scheme) on the adoption of shore power and system cost are also explored.
