Network industries are built on transport infrastructure such as telecommunications waves or data, gas or electricity, which are essential facilities.
These essential infrastructures are monitored by regulators not only for the operators to have a concrete right of access but also for a complete network of these infrastructures to be built in a space, especially in Europe, for example to achieve a European railway system.
These infrastructures also exist in banking, financial and insurance matters, which it would be futile to oppose too easily to Network industries, as financial centers are based on huge computer systems, internalized clearing houses, which are themselves Infrastructure, deserving Regulation.
In this way, the optimal infrastructure solidity, the Regulator having its final responsibility in a permanent control over the manager, whether the State or an operator - whether the operator is an operator Public or a private operator -, and the competitive dynamism of the sector that the system can also entrust to the same regulator.
This is particularly the case in Financial Regulation, which aims to optimize the places, which compete with each other, and their respective security, which itself constitutes a competitive advantage, common to all operators.
