How does the license plate quota policy affect NEV sales?

After the license plate quota policy intervention, the results ( Fig. 2) illustrate that the actual cumulative sales of NEVs increase rapidly, and the cumulative sales of synthetic treated units still increase steadily, making a large gap between the actual cumulative sales of NEVs in each treated unit and its synthetic control.

Does license plate quota policy affect Nev adoption?

To promote the rapid development of NEVs, the Chinese government has adopted various incentive policies. This paper uses the SCM to quantitatively estimate the effect of license plate quota policy on NEV adoption, using DID method for robustness test, and obtains some findings and policy implications as follows.

Does Shenzhen have a license plate quota policy?

How do policies affect solar PV deployment?

Policies have a key role in increasing deployment of solar PV and decreasing systems’ cost. Meaning, as costs for solar PV systems decrease, solar PV becomes more competitive and as a result, deployment should increase . Additionally, as more solar PV systems are installed, its costs should go down [3, 4].

How can the solar PV market maintain its growth?

However, in order for the solar PV market to maintain and continue its growth, policy is needed to incentivize R&D commercialization .

Why do we need a solar energy policy?

To date, a large number of installed solar technologies have been due to policy. Studies have shown that the U.S. solar photovoltaic market is driven by federal, state, and local government incentives such as cash rebates, federal and state tax benefits, as well as production-based incentives.
