Carbon reduction technology selection mechanisms for low-carbon cities and innovative cities
Low-carbon city pilot policy and innovative city pilot policy are important policy tools for realizing the'dual carbon'goals and promoting high-quality economic development.Examining the choice of carbon emission reduction technologies for enterprises un-der different pilot policies is of great practical significance for saving production costs and enhancing the effectiveness of enterprise emission reduction.In light of these factors,taking profit maximization as the goal and under the assumption that carbon reduction tech-nologies include only cleaner technology and treatment technology without considering the impacts of other external policy factors,we constructed a production function based on Hicks-neutral technology to analyze the carbon reduction technology selection mechanism of enterprises under the three types of pilot policies.Furthermore,based on the panel data of 3 766 enterprises in 75 pilot cities in China from 2000 to 2019,the study verified the scientific validity of these technology selection mechanisms by applying the Hansen threshold panel model.It was found that the selection of cleaner technology and treatment technology in different pilot policies was based on the ratio of treatment technology to the outputs.Specifically:① If this ratio was at(0,0.5),under the pilot policy of low-carbon cities,enter-prises would choose the lower cost treatment technology;under the pilot policy of innovative cities,enterprises would lack the willing-ness to invest in carbon reduction technologies;under the'dual-pilot'policy,enterprises reduced carbon emissions by applying both cleaner technology and treatment technology,and they would invest more in the former because it had a quick effect.② If this ratio was at(0.5,1),when the cost of treatment technology exceeded 50%of the output,enterprises under all three types of pilot policies would choose the lower-cost cleaner technology to reduce carbon.③ The results of the heterogeneity analysis showed that under the constraint of production costs,non-state-owned enterprises,old enterprises,and enterprises in high-carbon industries would lack the incentive to increase their investment in carbon reduction technologies.Therefore,governments at all levels should guide these three types of enter-prises to enter the carbon trading market and stimulate the initiative of low-carbon technological innovation of these enterprises through policy subsidies,high-tech enterprise incubation,and the promotion of carbon reduction source-governance technologies,so as to ulti-mately achieve the reduction of total carbon emissions with the smallest carbon emission reduction cost.
