According to the current power supply focused reform in China, a dual-channel and multienergy supply chain model is constructed. The supply chain has a new energy enterprise, a traditional energy enterprise, and the State Grid that is the retailer. New energy company and traditional energy company sell electricity to the State Grid at wholesale prices, and at the same time they enter the market to retail power products. Multiequilibriums and their practical significance are discussed. The complex dynamic is investigated using a bifurcation diagram, Lyapunov exponent, parameter basin, and fractal dimension. In this multilayer supply chain network, the price adjustment of the State Grid will make the entire supply chain face greater volatility risks, and dual-channel suppliers, that is, new energy and traditional energy companies are also involved in this volatility. Further, considering the sticky information, the sticky expectation of electricity price is built for studying the lagging electricity price. The dynamic characteristics of the sticky model are investigated, and new phenomena are discovered: 3-orbit bifurcation and mutation appear with fractals. This means that prices continue to swing and oscillate on three tracks. Through comparison of the fractal dimension, an important conclusion is discovered: the purpose of sticky expectations for electricity prices is to stabilize price fluctuations, but sticky expectations make the market more complicated. The article provides a strategic reference for exploring the power market in China.

Considering the multienergy structure of the electricity market and supply-side competition reform in China, a dual-channel and multiproduct supply chain model is constructed. There are three players in the game model: new energy company and traditional energy company provide energy for the market and the State Grid at the same time. The State Grid is a retailer who buys electricity from two companies and supplies to the market after converting and transmitting the power. Three companies can invest in grid management for saving energy and reducing losses. The energy loss rate is an exponential function of line loss investment. Through the bifurcation graph, Lyapunov exponent, and the basin of parameter, the complex characteristics of the investment market are analyzed. It is interesting to find the Grazing–Hopf bifurcation which usually occurs in nonlinear circuits. The mixed expectation of bounded rationality and the naive expectation is conducive to suppressing the bifurcation and chaos of the market. When external shocks occur, the control model has good robustness.

Dual Channel Supply Chain

A two-level dual-channel supply chain model was established in which retailer had his own direct channel. Game model was constructed based on two cases of decentralized and centralized decision-making. Pricing strategies of manufacturer and retailer were studied. Impacts of different channel and different sale entities on manufacturer and retailer were examined. Results show that when channel substitution increases and market share of retailer direct channel is small, retailer should choose to give up direct channel and focus on retail channel sales and take direct channel as means of propaganda and brand promotion. When the difference of sale entities reduces, consumers can get more surplus.

The Impact

As a weapon for economic development, green finance plays an important supporting and promoting role in the economic recovery and transformation of enterprises in the post-epidemic era. By constructing a dual-channel supply chain model, this paper considers two situations in which manufacturers participate in carbon trading and green finance loans, and uses Stackelberg game to study the impact of different situations on participants’ profits and emission reduction decisions. The results show that: under the carbon trading mechanism, the carbon emission reduction level of the manufacturer is inversely proportional to the relevant price, and the demand and profit of the two channels increase with the increase in emission reduction; when carbon trading and green financial loans are carried out at the same time, participants have lower profits, but with the increase in emission reductions, it is still a growing trend.

Simulation Results

This paper analyses the dynamics of dual-channel energy supply chain model with heterogeneous retailers (as regards the type of expectations’ formation). On the basis of analyzing the stabilities of four fixed points in the three-dimensional dynamic system, local stable regions of Nash equilibrium are obtained. Effects ofSon the stable regions and profit are studied. Simulation results show that the adjustment of price speed has an obvious impact on the complexity of competition. The performances of the model in different period are measured by using the index of average profit. The results show that unstable behavior in economic system is often an unfavorable outcome. So this paper discusses the application of parameters control method when the model is in chaos and then allows the oligarchs to eliminate the negative effects.
